Sold, thank you
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.
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”
Edge length 7.5”
Weight 10.7 oz
Extra grippy 3D machined scales
Black oxide treated 18-8 stainless steel fasteners
Spec Ops Combat Master sheath can be hung from a belt, mounted to all duty belts, is M.O.L.L.E. compatible and jump certified.
David Brown Kydex sheaths with TecLoc are custom made for these knives and are well designed and well made.
There are two knives in this sale.
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 in a Dave Brown sheath is “field grade”, “as machined” and stonewashed. It has black micarta scales machined in a diamond quilt. I sharpened the clip an inch. This will make a good pig shanker $290 SOLD
The second fighter in a black Spec Ops sheath has a ground finish. It has black G10 scales machined in a diamond quilt. $320 SOLD
If you want a different sheath, let's talk about it
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
