I have one goal, to make fine knives, working with clients and their ideas and also independently designing, and improving my skill year after year. A great deal of this effort is continually invested in embellishment. Embellishment is one of the major factors in a knife's appeal, value, and unique nature.
If you are well-versed in fine custom knives, you might realize how rare it is to find an artist who does it all. Most knife makers excel in one or two phases of the tradecraft, and often leave embellishment to other artists. I've never been comfortable with someone else completing my projects, so I don't farm out or contract other's work. Starting with design work, I make the blades, fittings, and handles. I make the sheaths, stands, and cases. I photograph, detail, archive, and create and maintain this website. In all of these pursuits, it's surprising to discover that one of the most time and skill-intensive areas of focus in a fine knife is the embellishment.
There is an old saying that an artist's work is never finished, that he merely abandons it at some point. This is the artist's bane. I may be happy with the piece, and indeed, it may look complete to others. But to me, a piece often isn't complete unless it's tastefully embellished. These are, after all, handmade custom knives, so some unique handwork seems necessary and appropriate. Handmade custom knives benefit greatly in value and investment quality from fine embellishment. Beyond all these reasons though, is beauty. Beauty in knives means a particularly graceful, ornamental, or elegant quality.
Beauty cast upon weapons and tools may seem foreign to many Americans. That could be because we are a utilitarian culture, producers of usable, reliable goods, meant to be work-ready, dependable, and tough. I suppose you could say Americans themselves are that way. For whatever your political style, one thing is certain, we're a hard-working society, perhaps the hardest-working in the world. I don't want to get into a geopolitics here, but I believe that is one of our greatest attributes: that we work hard and are prolific producers. That could be why we value utility. We want tools that work, vehicles that work, machines, products, and people that work without glitz, glamour, or gaudiness. And somewhere along the way, we've misplaced our interest in beauty. Beauty is superficially seen in Hollywood and the media, fleeting and often insincere. In hard goods, useful tools or items designed to last through the centuries, though, the beauty instilled by the original artist lives long after his presence.
What is beauty? Is it the gorgeous supermodel spinning around a signpost in Manhattan with a lean figure and pigments accenting her facial details? Is it an oil painting by a master who lived four hundred years ago? Is it a southwestern sunset? One thing about beauty, it is like the ocean, you know it when you see it. And though you may experience beauty in a simple, utilitarian custom knife with clean lines, a rudimentary blade, and flat, polished bolsters, you might wonder what it would be like if it were finely detailed with every inspiration the artist could apply.
If beauty isn't reason enough, take a look at it from the descriptive verbiage: customization, which means to build, fit, or alter according to individual specifications. Embellishment makes a knife unique, particularly if the embellishment does not exist on any other knife. This makes the knife "one of a kind," thus increasing its value. Even mass producers of knives see this worth, and that is why they number "limited edition" styles of knives. Sometime in the future, this etched application of a numbered set is supposed to make a knife appreciate. It's a sad attempt to borrow the idea and mimic true customization by master craftsmen. More on that below.
For the macho types that only consider blades as tools, weapons, and pieces of sharp metal to be torturously utilized in cutting line, scraping metal, stabbing your enemy, or dressing game, this is for you: One of my finest clients, a rather famous person and well-educated historian of war and military engagements looked at one of my fine embellished daggers and said: "It would be an honor to have that shoved in your guts." There you go, forget beauty, it's about honor!
I always try to remember that this isn't about society, or value, or culture, or even me. It's about you. So when I take the time and considerable effort to embellish a custom knife, I am thinking about my client or patron, either realized or potential, and his interpretation of what I envision for the knife, sword, or dagger. Yes, the ideas and details are mine, but artistic concepts are shared, that's why they're art; like beauty, they're known when seen.

You bet; perhaps some of the oldest history we know. You've read on this site (I hope) on the FAQ page, the Blades page, the Handles page about the history of man's first tools and weapons. Throughout time, man has embellished his weapons. Some historians, archaeologists, anthropologists, and academics claim that this was an attempt to gain mystical power over his opponents or prey, and these scholars might even attach a religious significance to these markings, carvings, inlays, imagery, and extra work for the artist. I have a somewhat different slant. While not discounting those reasons, I think that too many trained intellectuals seek to find esoteric, superior motives as their expensive training and great investment of time and study dictates. After all, these are well-trained professionals, and someone has paid for that education. But most of them have never made something with their hands, carried a piece of steel at their side, used it to get them out of a pinch, and wanted to recreate or honor the significance of that experience. We value the experiences we have had and will have with an edged weapon or tool, so we impart imagery to it to reflect that. The maker must mark his effort to set it apart, and the user associates the item with an event, and that is how embellishment starts. Then, the man who carries the knife, sword, or dagger must relate to others this experience. So the piece is made with a depiction of a great battle, or the image of an animal, or his name, or his service dates, or his quest. That way, he can show it to his allies, cohorts, and strangers and account the experience, brag, or maybe even lie...
And then there are the flourishes. Why would we put plants, and paisley (dolphin and fish imagery), and curves, and flowers, and flowing lines on our tool or weapon? I believe this imagery does several things. Depictions of living things relates the inorganic nature of the cutting tool to its environment and reflects life back into the inanimate edged tool. And the flowing lines reflect motion and the fluid movement capable in the knife, sword, or dagger. It relates the knife to its use or environment. Now, I could get into the genetic need to relate patterns within our mental constructs, perhaps derived on a genetic level through unique human brain processing by illustration and elaboration, but I don't want to stray too far.
Please remember this: some of the most valuable historic items in existence today are knives, swords, tools, and weapons, and the most valuable of these are encrusted with jewels and gemstones, elaborately engraved, etched with images, carved, gilded, inlayed and awash in precious metals, and hidden away in the vaults of private collectors and museums.

It's true, the best knives have names, not model numbers. A model number is just a number. It's a cold, impersonal registration of one of a long line of repetitive patterns, suggesting a factory has produced all the numbers leading up to the model, and will crank out a never ending list of faceless numbered pieces after that number. Your model numbered knife is somewhere in the monotonous string of digits.
A name personalizes the knife. It adds to the knife's flavor, animation, and style. It defines the knife by purpose or intent. While I try to stay away from knife names like Slasher, or Stabber, there is some mystique in a name like Bulldog or Ladron. Incidentally, the name Bulldog comes from the Bastogne Bulldogs of the 101st Airborne, the Battalion of my son, and their mascot. He designed this fine knife for combat use. Ladron is named for a mysterious singular mountain in south central New Mexico, and it is the Spanish word for thief. It was a favorite area to hike when I lived nearby, and I would have loved to carry this knife there.
Many of my knives have southwest and specifically New Mexico place names. The Land of Enchantment has a flavor that suits artistic creation, and the place names seem appropriate. I've lived here nearly all my life, and I try to honor those many memories with a fitting name to a matching style of knife.
You've probably noticed that many of my knife names originate in the stars. That is, they are names of stars in the cosmos. Many of these patterns are Gerry Hurst's, left to us when he died. He didn't have names or numbers for them, so in order to catalog them, my wife and I reached for names he probably would have liked, names of the heavens. Then, I carried on the tradition in new designs. and even name some for features and areas on planets in our own solar system. Somehow, cruising through the names, one will stand out as fitting and complimentary for a pattern. Take the name Horrocks. It's a crater system on the moon. The name sounds like a powerful warrior, so how could it be more fitting for a large, heavy, curved combat knife?
Some of the names on my patterns are the names of our grandchildren. I'll bet you can't tell which ones. Hint: no, it's not Draco!
Some names describe the blade shape itself, like Sheepsfoot, or Reverse Paring, or Half Moon Skinner. Other names describe the use of the knife like Game Set: Caping, or Carving. Other names bear the names of the designer who worked with me on the design of the knife, like Wardlow Bowie, Berger, or Gibson Trailhead. You'll also see the designation Magnum on a few of the blades. These are larger evolutions of an original design, for example the Nihal Magnum is a larger combat version of the Nihal.
The neat thing to know is that a name gives a knife personality. We are creatures of words, and words mean things. Our language is more than just a way to share and express, it is a way to characterize, personalize, and animate those objects we use, cherish, and ultimately leave behind.

Etching is the process of cutting into a material (usually metals) with acid. In the old days, a layer of beeswax and asphaltum (ancient Egypt) was coated onto metal and a burin (or scraper) was used to scrape away a design in the wax, then the metal was dipped or coated in acidic liquid, and the exposed metal was etched (cut) away. A lot of armor was etched this way, as were countless swords, daggers, halberds, partisans, maces, and other early weapons. Firearms, too were etched. The cut, being rough and irregular, was usually darker than the surrounding metal. Etching shows up best on a mirror or brightly finished metal as the cut is dull and grainy.
Today, there are still some artists who etch in the traditional way. Unique, multi-step etching processes can create great works of art, and the process is well demonstrated in the jewelry industry. Many metallic items today are etched, nearly all machine tool cutters and drills for instance, and many metal pieces that need to be permanently identified are etched in industry.

Today, the etching process has been industrialized, masking methods improved, and electric current added to the process to aid in etching corrosion-resistant metals. In the knife field, factories etch imagery in blades, often in "limited edition" production runs, with some animal, event, publicity-driven cause, motion picture promotion, or just about anything they think will sell their products. Since these processes are automated, the object is speed of production, not quality of image or detail of the cut, so the etching is rough, with fuzzy borders, very shallow, and poor. With laser engraving some automated processes can personalize or individualize the imagery somewhat, but the laser too, creates a fairly rough image.
My etching process is different. I worked for six years to perfect the process, and have line resolutions to 1/100,00th of an inch. My etching is clean, crisp, and even. It never has fuzzy edges, and even if you examine it under a microscope, you'll be impressed. The etching is deep, dark, and permanent. How do I do it? Sorry, my process is proprietary. Several companies and numerous knife makers have begged me to sell the process to them, but I haven't. Maybe when I'm older, but I'm not done playing with it yet... I've got a few elaborate projects, etching of gemstone, and other things I've got to do first.
You've probably noticed that nearly all custom knifemakers etch their name or maker's mark into their blades. They use a well-known process sold by a company that advertises in knifemaker magazines, catalogs, and publications. The process is simple: a tiny sponge is soaked in an acidic solution, it's applied over a small plastic mask to the blade, a weak electrical current is applied to accelerate the cutting by the acid. The image is dark, low resolution, very fuzzy around the edge, and not very deep. My makers mark is different. It's extremely small and resolute, with very high detail and deep penetration. Most people need a magnifier to read it. My mark from 1988 to 2006 was "JaFisher Quality Custom Knives" in script, with two flourishes filling out the logo. The "JaF" is in a butterfly form. My earliest knives just had the butterfly "JaF." The entire logo is .530" wide on most knives, and I've even used a smaller one where space is limited that is .300" wide! Since 2007, my maker's mark is simply my "JaFisher" signature, but the quality has not changed. It's clear, sharp, and well etched. Read more about my own maker's mark on a dedicated page here.
Beyond the maker's mark, I can etch just about anything in a blade like military logos, emblems, text detailing names, service dates, and important events. I've etched animals, flourishes, faces, foreign language characters. Just about anything you can imagine can be etched permanently into the blade, bolsters, or metal components of the knife or sheath. I even etched gemstone handles.
What I charge for custom etching depends on the image. Obviously, high detail graphics will cost more than text. Sometimes, it is more effort to custom design the artwork than to execute the etching. Each etching is quoted on an individual basis.
Is my etching deep? You won't live long enough to hand-polish the deep cuts out of the metal. The only way to remove it is to regrind the blade starting at 40 micron (about 360 grit) and sand the blade back to high polish.
In the past, I've etched bead-blasted blades. I wasn't happy with the fogging and fuzzy quality of the etching, so I now only etch finely sanded or mirror polished blades. This takes advantage of the fine resolution, high detail, and stark contrast of the etching cut.
Once upon a time there was an old word, "jimp" that came from North England and Scotland, meaning neat, handsome, and slender in form. The knife industry designated regular machined cuts or cross-hatched patterns on the back of the spine of the knife to improve traction of the fingertips "jimping." They still call those regular spaced machine made cuts jimping, but the in the custom and handmade knife world has evolved into artistic filework. Jimping may be machine cut by automated slitters, mills, or blades, but filework must be hand-cut.
Jimping, and thus filework, has evolved into a highly decorative art form, sometimes even accented with engraving and precious metal inlays, differential anodizing, finishing, and bluing. The edge of the spine is its own canvas, and it seems every knife begs for its own style or pattern. My filework on one blade may take from one to eight hours to complete, each cut performed while bent over a filework vise with proper magnifier. I use all hand files, needle files and micro files (they're the size of a toothpick) and special layout tools and protractors. The pattern is worked through a succession of cuts, then worked over for accuracy and uniformity. File cuts do not need to be smoothed or sanded, and sometimes a rough surface is better because it causes a visual contrast with the polished blade. Filework and edgework personalizes a knife, and is an absolute indicator that the knife is uniquely hand made, and still functions to stop the hand or fingers from slipping on a slick spine.
No factory made knife will ever have or imitate fine filework. This particular skill, working on a curved surface down a tapered, narrowing tang can only be achieved by a skilled hand. This makes a well-made, fileworked knife unique and increases its long term value. The quality of the filework is a direct indicator of the significance of a custom knife, and you don't have to be a trained appraiser to see this worth. The human eye is drawn to arrangements and regularity in repeating patterns, balance, and style motifs. Take a good, close, hard look at the filework, and you'll know the quality and thus the value of the knife.
"Mr. Fisher,
some of the first file-work I ever saw was in a Blade Magazine (if memory
serves), and the name attached to the knife photo was yours (that I remember)...Since then,
I have sought to breathe that extra bit of life into a knife as you have, and I've been
getting some high praise from folks 'round here when they see what I do. I am quick to
steer them to the real pros when they exclaim over my handy-work, and more than once
I've spoken your name as one of the key motivators for my endeavors. I happened
across you today while researching something, and wanted to stop by and thank you for being one of
the catalysts that occasioned me to become an embellisher of people's steel companions. If you
are so inclined, I have an account where I keep pictures of my efforts, and I would be honored if
you were to stop by and offer your critique....Thank You Mr. Fisher, for providing the
light that I'm sure has been a guiding beacon to others than just myself.
Peace to you and yours, J."
Hi J. Thanks for writing, and thanks for your encouragement. I did look over
your picture album, and it looks like your work is improving as it goes along. The only reasonable advice I can offer is
to keep at it, keep practicing, and take plenty of time on your projects. If you're like me, you can't stop making even
if you wanted to!
Thanks, Jay
Thank you, Mr. Fisher, for your quick response. I am teaching myself how to
build knives and the filework is my favorite part. I always look to your website for inspiration
and I hope to be half as good as you one day. Thanks again!
--G.L.
On one knife maker's web site, I read an amusing (and astounding) comment. He claimed that filework does not have to be symmetrical or balanced, and sometimes it looks better when it's not. What? Okay, maybe I'm not understanding his idea here. If a knife has good filework, you know it. Irregular, out of balance, and non-accurate filework does NOT look good, and trying to tell people it does is just a way to cover for bad craftsmanship. Because filework is done by human hand, of course it cannot be perfect. But if you're going to pay hundreds (or thousands) of dollars for a custom or handmade knife, it better be very, very good!
What to look for:
I keep a pattern book of my most favorite designs, and I offer three lengths of filework:
Filework and edgework for folding knives is a bit different. Good filework extends from the blade all around the spacer/spine, and usually includes the liners. Anodized titanium liners and lock spring plates can be fileworked as well as the blade and spacer/spine. The inside of the knife should also be finished, and the junction of the blade to stop on the spacer/spine should be seamless.
Here are some fileworking process pictures. It may take hours to filework a knife, and I may have a batch of 20 knives to do at once!
There are two types of engraving I'll address: hand engraving and machine engraving.
Hand engraving is the cutting away of metal with a small tool called a graver, chasing tool, or chisel. It's done by hand, sometimes with the assist of a hammer, tool, or vacuum/pressure hand piece. No matter the device or assist, it is all controlled by hand. One could write a book on engraving (there are many), and hand engraving is one of the highest value additions to fine custom knives. It has a deep history and kinship with fine weaponry, and there were (and still are) people who spend their full-time work lives only hand-engraving metal, usually jewelry, firearms, and knives. The wide variety of cuts available through a skilled engraver is astounding, ranging from almost imperceptible fine scratches on the surface, to deep, dark background relief, and even penetrating holes through the metal. Hand engraving has character, the style of the engraver is apparent on every surface.
The greatest value brought to already complete custom knives is usually through hand engraving. A good engraver will often charge $150-$300 a square inch (that's one half inch by one half inch)! So to engrave one set (that's both sides of one bolster pair), the engraving alone will cost $200-$800, depending on the size of the bolsters, the material, the engraving design, and the engraver himself. Often, an attempt is made to improve the value of a fine custom knife by sending it out to an engraver. This usually works, but the engraver often has his own ideas about the artistic style of the piece, and he imparts that flavor to the engraving. So many knives look "gussied up" instead of completed with a singular, uniform design idea. Then if the knife maker or owner sends it to a scrimshander for scrimshaw, and then a leather worker for a fine sheath, eventually the whole design idea looks broken up and in the worst case, schizophrenic. Now don't get me wrong; there are some fantastic engravers out there that can add thousands of dollars of value to a fine custom knife. The knife owner or maker must determine whether that value is well applied.
I've seen many knives that look like this and the first impression is a "busy" overall appearance. When you look at the components, each one has it's own merit, but together can be overwhelming. How to rectify this: one artist, a singular idea or concept, executing all aspects of the piece, blended into a solid, interesting, and beautiful idea. The added benefit of this is that the sole artist is also responsible for the entire work, therefore accountable. If anything goes wrong, or is substandard, or is questionable, the maker is the source for rectification.
Ultimately, when the individual maker creates all parts of a custom knife and its accoutrements, he then learns and grows at an increased rate, as consideration is given to specific construction techniques that will be important for those later applied embellishments. And that greater rate of growth, accomplishment, and skill leads not only to a better knife, but a better overall investment for collectors. Remember, the value of a custom knife and collection is directly attributable to the maker, his skill, history, and longevity making knives. Read more about that on my FAQ page, "What is the value of investment knives and why?" here.
I try to be the best engraver for my own work, and I strive to learn and improve on every knife or project. It is a lifelong pursuit, continually changing and growing until I stand at the feet of God and my lessons here are finished! Thankfully, He has given me room and time to learn.
Jay,
You have taken my breath away! They are absolutely beautiful, in fact I am lost for words, I am just
sitting here with a stupid grin on my face, never in my wildest dreams could I have imagined such beautiful
knives. The display stand is a masterpiece of functionality and elegance.
Can’t wait to get my hands on them!!!!!
Thank you so very much

Machine engraving is done by machine, a computer driven X-Y-Z axis tool. The piece to be engraved is rigidly clamped or held, and a variety of cutters can be worked against the piece, cutting away metal or scribing a series of lines in the surface. The finest cuts are with a diamond-drag stylus, heavier cuts are with rotary carbide cutters, mills, and burnishers. Burnishers spin and drag across the work, carving a regular surface in it. Good machine engraving takes a skilled computer artist versed in CAD/CAM (computer aided design and computer aided machining) to get good results. There is also a lot to be said for spacing, text and graphic relationships, arrangements, and placement. On knives, you also have to be aware of wear areas and height lost to sharpening. In the custom handmade knife field, not much machine engraving is being done by the singular knife maker, but I'm happy to be able to accommodate my clients with this service. Some stunning and original designs can be created, as well as personalization, recognition, and commemorative pieces.
Most people might recognize machine engraving as originating in the awards and recognition industry. Though every trophy and signage shop may have machine engraving services, it is seldom that this process is applied artistically to knives. Usually award recognition deals only with text, and few graphics are included. In custom and handmade knife making, it's a relatively new art. It will be interesting to watch in this field, as there is great potential in this evolving process, skill, and technique. I offer a wide range of machine engraving here in my studio, I can work with almost any text and graphic images in high resolution and detail.
Engraving is an ongoing learning process. My early engravings are like most artists, rough and crude. You'll see some of them posted on this very site. Every artist should progress, and my journey is no different. I'll do my best to improve my engraving, as I will with every pursuit. In these arts, you never "arrive" at mastery, you simply keep working, keep applying, keep striving for a better result. Since man is never perfect, no engraving or artwork will be. Artists can only hope that progression will be demonstrated in their works, and patrons will continue to believe in their efforts.
Every engraver has his own style. That style may be copying another's work, or it may be copying the style of the school where he learned to engrave, or it may be truly unique. I strive toward the unique and original based on historic creations.
There are many fine engravers out there, and most have three styles of cuts that they do. These are "bank note" engraving (a deep relief scroll work style), fine English (a light, tiny scroll style) and Bulino (very small lines or dots recreating a high resolution image). These are all beautiful styles, and that is why they're so popular. The commonality of these styles also explains why they're accepted so readily in the trade. If you've seen some nice work in either of these motifs, you know what to look for in engraving. I even like to work in these styles now and again, but they are not the whole stock and trade of engraving. There are literally thousands of types of cuts one can achieve; the designs are boundless.
I read in one internet posting a response that only a few styles of engraving are "accepted" within the knife collecting community. According to the person who posted it (who claimed to speak from a position of knowledge on the subject) the only type of engravings found in history are these few styles, mainly scroll work. I was stunned. Today, you can pick up hundreds of texts on historical engravings. Every one of them is different, for man has been scratching and cutting metals for as long as he has had them. Before that, he scratched and carved pottery and stone. There are literally thousands of styles of cutting. I would encourage this "expert" to pick up a book that details Victorian engraving, Persian engraving, or bronze age engraving. There are Egyptian engravings, early engravings, and savage engravings. Historical styles of many kinds of artwork have developed into engravings. There are Gothic styles, Byzantine styles, Moorish styles, Roman, Pompeian, Greek, Etruscan, Blazonry, and Renaissance styles of artwork, all demonstrated by and featured in engraving. As I continue to improve my engraving, I hope to apply more of these styles myself, and not be confined to only scrollwork.
I try to match my designs to the knife style and flavor. This means experimenting with unusual, non-standard cuts. This also means cutting non-standard materials. For example, I engrave a lot of 304 stainless steel. I know of few engravers who do this. Why? Because it's 25% chromium and 8% nickel and extremely tough. It snaps off the cutting points of the hardest, toughest gravers with just a few minutes of cutting. It has to be cut with a pneumatic hammer assist machine such as a Gravermeister® or Gravermax®, because the hand alone is not strong enough to control and execute good cuts in 304SS. Why do I cut so much 304 stainless? Due to the high alloy content, this is a permanent, zero-care steel. The only thing that will corrode 304 is strong acids and caustics. Whereas many knife engravers prefer the clean (and relatively easy) cutting of carbon steel, the engraved carbon steel must be meticulously cared for, or it will rust at the slightest opportunity. With today's stainless steels and engraving adjuncts, why settle for steels that easily corrode? Why saddle my clients with having to constantly oil, wipe, and worry about their steels rusting, corroding, or pitting and their investment degrading?
Of course, I can and have engraved carbon steel, and I also engrave standard blade and bolster metals, like 440C stainless steel, O-1 tungsten-vanadium alloy, ATS-34 stainless steel, CPMS30V, CPM154CM, mild steel, nickel silver, sterling silver, and brass. I experiment with a wide variety of styles and cuts, striving for improvement on every piece.
It was once said that "Any style that is not boring is a good style." I agree.
Though I make custom knives, I reserve the right to work up the engraving design, pattern, and style to match the flavor of the piece, so I seldom accept artwork for the engraving from potential clients. This is different from personalization, such as etching a person's name, a military emblem, a logo, or text on a blade. For that, see Machine Engraving and What is Etching? above.
What I'm talking about is submitted artwork for hand-engraving like animals, people's faces, scenery, buildings, and any other artwork and graphics that a client may wish to have hand-engraved on a knife. There are a few reasons I don't offer this.
If you insist on personalized engraving or having a favorite image engraved on a knife, there are many custom engravers out there who will work with you. You may commission them to engrave any knife, including mine, and that may be a good option for you.
No, I also engrave and hand carve gemstone, scrimshaw ivory, tusk, and bone, inlay in wood, execute mosaics of gemstone material, inlay gem in metals, inlay metals in gem, carve the fittings and pins, and apply the same techniques of knife embellishment to sheaths, cases and stands. See pictures and details of those on the "Sheaths" page here, and the "Stands" page here.
For an example, here is a picture of a knife with the original
design draft. It has a hand-engraved 440C high chromium, mirror polished hollow ground stainless steel blade,
hand-engraved with a custom design, and the handle is
sculpted and has an inlaid blued steel pommel and guard, a mosaic inlayed
gemstone handle, with guard inlays of carved ivory and pommel inlays of
solid opals.
Here is a picture of a knife that has hand-engraved 304 stainless steel bolsters, matching engraved leather sheath, and a matching
engraved Petrified Palm Wood Gemstone handle. The design is Victorian, and the gemstone engraving was cut with a fine
diamond stylus into the hard jasper gemstone.
Millwork refers to any cuts on or through the blade that is done by milling, which includes drilling holes in blades, bolsters or handle areas of the knife. There are several reasons for this practice.
Milled slots with fileworked edges, complex crosses, waving curved designs through the blade, carving, geometric arrangements, and precision attachment holes: all these are available. In my own knives, l make sure the milled angles, corners, edges, and shapes do not cause stress risers in the tool steel, which is another reason I heat treat my own blades.
Titanium is used mainly in my folding knives for springs and liners. These are the necessary parts that support the handle scales, bolsters, and pivots. Titanium is used because it is strong and lightweight, essential when the handle of a folding knife must be larger than the blade in order for the blade to fit inside it. Titanium is not a hard steel; its advantage is that it is lightweight, tough, springy, non-corrosive, and somewhat wear resistant. It supports fine filework, and accommodates threads and milling well. Another feature of titanium (I use 6AL4V) is the ability for the surface to be anodized. Anodization is a treatment where the surface is oxidized to a passive nature, and the process creates a significant oxide film thickness that causes optical interference, or more simply, the reflection of colors. The treatment is very thick as treatments go, in the order of up to .2 microns. It is not easily worn away, and maintains the color for decades, perhaps indefinitely.
Though heat may be used to oxidize the surface of titanium, I use a more controlled chemical method. The method consists of cleaning, etching, pickling, and a bright dip, followed by the chemical anodizing treatment. This may be done several times, the colors can be contrasted on different parts of the titanium, or graduated for interesting effects. The process requires masking, finishing, an electric power supply, knowledge of some chemistry, and a picture of the set up for the basic process is below, with some anodized knife projects.
Thanks for taking the time to view my "Embellishment" page for custom and handmade knives. Please check back, I'll be adding to this page as time and projects allow. Embellishment of fine custom and handmade knives is an evolving process, and I'm honored that you've come here.
