Reviewing the Caruthers 3V Fighting Shiv

Recently I purchased a truly wonderful fighting knife from a talented builder. Nathan Caruthers can be found on under the name Nathan the Machinist. After viewing his video and the testing he put his blades through I was able to purchase knowing that regardless my results it would be a fine addition. Little did I know how nice this knife really would be.

When it arrived within a few days of ordering I was surprised. Average turn arounds for custom builders are almost always in the months unless they are selling one already made. His response time was extrodinarily fast and safely shipped. As I danced around happily and unwrapped the piece I realized that this was going to extremely fun. Within minutes I had tested the edge it was shipped with and after picking up the pieces of my left arm from the table and placing them in ice I wrapped a tourniquet tightly to stop the bleeding drank another beer aqnd proceeded to the chopping and hammering tests. (Yes folks it is that sharp though I neither had a beer in hand or a missing limb.)

As for grips it fits the hand amazingly, balanced like no other knife I have handled and I have handled and own hundreds from Benchmades through Emersons and dozens of wonderful fixed blades as well. Folks, I cannot say enough about this knife. Even though it is a fighter by design, it is an amazing blade that very easily can do far more.

Now I have thrown this knife several times using the no flip throw I prefer, it functioned amazingly as a thrown knife. I really recommend this knife – share the video and lets help Nathan the Machinist become a BladeForums household name! The following videos are quite short, the first less then 4 seconds and the second right over a minute. Enjoy them both and comment here to let Nathan know how much you want to get one of his wonderful custom pieces.

In Nathan’s words here are the blades SPECS: The Combat Shiv is made of CPM 3V. It’s designed as a stabbing weapon and 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.

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

David Brown Kydex sheaths with TecLoc are custom made for these knives and are well designed and well made.
