View Full Version : Knives and other tools I make
09-10-2013, 11:08 PM
Here's a couple of the things I make. The only CNC on the knives is the laser engraving, and sometimes I'll cut the profile out with a waterjet or plasma.
Some general purpose outdoorsy knives-
Note his boot knife too. Only for wear with shorts or kilt, of course.
And a larger one of a similar design- "Something big enough to take apart an elk. And then a little bit bigger"
Here's a couple kitchen knives- Local olive wood on one, Micarta on the other.
These are some EOD probes I'm helping develop and produce. If you're EOD and looking for what a superior probe, shoot me a PM.

great looking stuff!

Are you just showing everyone what you can do or you offering products for sale?
If you are trying to sell knives, some information about the steel used and the dimensions would be extremely helpful.
By the way the blades look beautiful.

Some of both. All of those are sold, but I'm always looking for more orders. :D
Mostly I use 5160 and 52100, but I have some others too (1095, 15N20, N680, recycled leaf springs and files) depending on application. .060" for fillet knives up to .25" or more for the big outdoor stuff.
More up here- https://www.facebook.com/CosiminiKnives No regular webpage yet; I really need to get one up and running.
Do you make anything with a clip point blade?

targetarcher : That first photo is *****en what price do you have on that one...

Are these blade blanks, or hand ground?
What is the thickness on that top blade?
09-11-2013, 8:42 PM
wjc, Thanks! I have, but I don't think I have any pictures handy. They aren't any harder to do, in any event. (Now, recurved hollow grinds, on the other hand, I still need more practice on. I'm working on a good kerambit for a friend.)
Dano, That pair went for around $600, including sheaths.
Or, if you mean the giiiiiiant black and blue one, that one was also about $600, including sheath.
Barbarossa, those are 1/4" 5160. They're all sole authorship unless specified. All hand ground, and even if I'm using CNC plasma instead of a bandsaw, there's significant hand grinding required to remove the HAZ.
I take them from here, (this one's still just a sketch, but would look great with a clip point too, wjc! )
Or here, (adaptation of an Argentine criollo knife for a Vermont fly fishing guide, 7" blade, colors inspired by the Eastern Newt. Design goal is "A kitchen knife that can prepare a stream lunch and then fight off a bear")
Chunking them out of the above steel
Rough profile grinding
Depending on the stock thickness, I'll either heat treat at full thickness or do a rough grind before heat treat. (the three on the right are by a friend who was learning)
And then more grinding, lots more grinding. Both for stock removal and scratch removal with progressively finer grits. Client asked for a sharpened spine on this fillet knife, says it makes quick work of panfish.
Making it shiny (sometimes). Oooooooh shiny. This one's based off a Chuck Stapel design that he's said I can use. Great little skinner pattern.
Fixing handle on with a combination of pins (there's a couple of internal hidden pins in there too, in addition to the visible one) and adhesive.
Rough grinding handle and then everybody's favorite, hand sanding!
And then just a little finish on the handle, maybe some rust preventative on the blade, sharpening, sheath making (if I'm doing one for the blade, not always) and it's done.

Nice work ! The hollow grinds look super...
09-12-2013, 8:01 AM
How long did it take to acquire this skill level?
09-12-2013, 8:32 AM
OP, its refreshing to see someone that knows what they are doing. Great looking stuff. Sure miss having a large belt grinder like yours:(

CNC day; I'm working on a G10 pattern (small production run) that is California compliant.
"2010 California Code Penal Code Article 6. Undetectable Knife PENAL CODE SECTION 20810-20820"
20810. (a) Any person in this state who commercially manufactures
or causes to be commercially manufactured, or who knowingly imports
into the state for commercial sale, or who knowingly exports out of
this state for commercial, dealer, wholesaler, or distributor sale,
or who keeps for commercial sale, or offers or exposes for
commercial, dealer, wholesaler, or distributor sale, any undetectable
knife is guilty of a misdemeanor.
(b) Notwithstanding any other provision of law, commencing January
1, 2000, all knives or other instrument with or without a handguard
that is capable of ready use as a stabbing weapon that may inflict
great bodily injury or death that are commercially manufactured in
this state that utilize materials that are not detectable by a metal
detector or magnetometer, shall be manufactured to include materials
that will ensure they are detectable by a metal detector or
magnetometer, either handheld or otherwise, that is set at standard
To do this, I'll be welding a steel ring through the handle, which can't be removed, before grinding the edge.
Anyways, I've been at this a couple years, but a love of sharp pointy things and art is genetic. I've a veterinarian for a father (who's excellent at his surgeries), a ceramicist/sculptor sister, and count several woodworkers, engineers, bowhunters, mechanics, and a blacksmith among my extended family.
So I took to knife making rather quickly. (I'll never forget the look on my mentor's face when he watched my first grind and said "Hey, you told me you'd never done this before!" :D ) But I've still had a long way to get here from there.
I've also noticed that the quality of my knives has improved with the size of my beard. Not suggesting that correlation implies causation, but we certainly can't rule it out at this point...
Blademan, yeah, it makes a lot of jobs easier, not just knifemaking! Hand fitting AK gas tubes, shortening rare Garand stocks to make bar stools (Just kidding! Don't shoot! Don't shoot!), deburring or chamfering stock for welding, etc.
Took a chunk off an 11" rail and reprofiled it for a 7" pistol barrel. Relieved it for proper free float too.

Nice work! Keep posting pic's. What part of SD are you in?
I've got a set of Tacoma springs I'd donate as a partial trade for a finished blade :)
09-16-2013, 8:27 PM
Thanks! I intend to; I've just been busy with a few other projects the past few days.
I'm on Morena; I work out of Makerplace (http://makerplace.com/). We're gun friendly there, too!
I'll shoot you a PM.

Turned this one out today. wjc, I remembered someone had asked about clip points, so I did one. Starting material was a leftover piece from a waterjet job. After grinding profile, I forged the handle to shape. It really has a reptilian tail sort of thing going on.
I still need to sign it, and I'll make a riveted leather sheath for it before I sharpen. Then I'll take some proper pictures-
And a couple days ago I rehandled a beat up French chef's knife. Fellow brought me this-
Check out this corrosion!
And here's what it looks like today. As he only wanted me to rehandle it, I kept a relatively coarse finish so as to match the blade. It's a working knife.

Gotta Love those Great Looking 1 of a Kind Handcrafted Knives
I have a Real Old Metal File that is Nice & BIG that would be Something I would like to have Custom Made into a Knife
09-29-2013, 9:22 PM
Digging the look. Nice work OP.
Dude...you do some nice work!
Love the handle on that French chef knife...
10-19-2013, 7:20 PM
I love the grind on that file knife, compliments the file texture very well, probably the best example of a file knife I ever seen.
10-20-2013, 10:31 AM
Very, very nice blades. Also +1 for being SD local.

Here's one I sent off to a Sons of Anarchy cast & crew charity golf tournament for Boot Campaign. I'm told it was a hit at the raffle! :D
And a heavy deba. More olive wood for the handle. Note that the back isn't actually flat, there's a very very shallow hollow grind!
Quick carbon steel bracer (armguard) I made as a sample. This could be tied on as it is, or attached with rivets to a larger leather piece. Goal for this one was to make it look like it had seen a few decades of traipsing around north of The Wall or Middle Earth. It's relatively easy to make new things look new, and it's not difficult to make old things look new. The real trick is to make new things look old.
