This is a new version of my heavy duty combat Shiv. It is designed as a stabbing weapon, it's made of CPM 3V and it is built to tolerate extremely rough use in demanding environments but is not so thick to not cut.
The edge thickness before sharpening was .020" and it was sharpened at 20 degrees per side, so it cuts, but at this thickness this steel with this heat treat can still cleave a concrete block without a problem. Wail on it, you're not going to break it. See video below.
These are sold, thank you.
The handle is ergonomically designed for a standard forward, reverse, saber and pinch grips for an average to relatively large hand. The tang is internally skeletonized. The scales are 3D sculpted CNC machined. The blade is made of ¼” 3V with a heat treat that has been optimized to maximize edge stability in insanely rough use. The blade has a swedge grind that creates distal taper and deep fullers that, together with the skeletonized tang, create a relatively light weight package (10.7 oz) that is supremely well balanced with thoughtful and deliberate distribution of mass that gives it a surprisingly light and lively feel in the hand without sacrificing tip strength.
The steel, Crucible CPM 3V, is a high performance particle metallurgy super steel with extremely high impact and torsional toughness. The heat treat has been tweaked to improve edge stability and edge retention. In this application it will easily tolerate abuse such as aggressive prying, punching holes in sheetmetal, cutting iron wire and even chopping through cinderblock. It is not stainless, but it has pretty good corrosion resistance.
Specs:
CPM 3V, tested 59-60 HRC, .235” thick at ricasso
Total length 12.75”
Blade length 8”
Weight 10.7 oz
Extra grippy 3D machined scales
Black oxide treated 18-8 stainless steel fasteners
David Brown Kydex sheaths with TecLoc are custom made for these knives and are well designed and well made.
There are three of these in this sale and a couple 6" utility fighters.
Rather than just take my word for it I made a video to illustrate the unusual durability of this knife:
[video=youtube_share;jAFQAp3Fo9I]http://youtu.be/jAFQAp3Fo9I[/video]
The first fighter is “field grade”, “as machined” and stonewashed. It has black G10 scales machined in a diamond quilt pattern. $305 SOLD
The second fighter is “field grade”, “as machined” and stonewashed. It has black micarta scales machined in a diamond quilt. The point is double edged so the tip cuts in both directions. This would make a great pig shanker. Not legal in some areas. $305 SOLD
The third fighter is ground. The clip has been thinned into a sharp double edge dagger grind. This is a seriously nasty meat eater. It weighs 10.4 oz. The scales are African Blackwood from an old stash of excellent dark stock. Black SpecOps sheath. Not legal in some areas. This is a one-of-a-kind. $390 SOLD
The fourth fighter has a medium grit ground finish. This is a 6" fighter in .165" CPM3V. It has black micarta scales scalloped pattern. $275 SOLD
The fifth fighter has a medium grit ground finish. This is a 6" fighter in .165" CPM3V. It has black G10 scales machined in a diamond quilt. $290 SOLD
If you want a different sheath I have SpecOps Combat Master Sheaths in their standard colors. They are M.O.L.L.E. compatible and jump certified.
Shipping in the USA is $5.
These knives are unusual because they are machined. I do this in my shop on industrial CNC machine tools. A WIP thread documenting their construction can be found here: http://www.bladeforums.com/forums/showthread.php/1048443
I take paypal, cash, check or MO.
Thanks for looking,
Nathan
