ON6504: OKC3S™ USMC Bayonet & Scbbard
Ontario Knife Company

This knife is used/issued by United States Marine Corps

NSN: 1095-01-506-3424

Designed to Marine Corps Military specifications for attachment to M16 rifles, this bayonet features a black coated clip-point blade of a proprietary carbon steel formula, with a small 1-3/4" serrated section at the base of the blade and a sharpened upper swedge. The grooved handle is very grippy and resilient, for use with or without gloves. The hard sheath with strapdown loops has drain holes for amphibious use, an embedded ceramic-coated aluminum sharpener on the back, and a sturdy ballistic nylon harness for attachment to load bearing equipment in multiple ways.

Handle is marked with USMC on one side (and on blade base) and 'globe and anchor' logo on reverse. Brown color is designed to match both woodland and desert camouflage schemes as well as to reduce IR signature.

Bad*** knife!
I use my knife every time im out in the woods. It wasnt as sharp as i would have liked but thats an easy fix. Long durabel blade that gets all the jobs i need it for done. The sheaths buttons could be some of a problem when you start using the knife but when you opened and closed it a few times all things about the knife is great!

OKC3S Review
The OKC3S impresses me and it is obvious that many people--including the end users--were in the design process. I favor daggers because of the double edge capabilities so the OKC3S doubles as a high penetration dagger, fighting knife and woodscraft knife. The edge came with would be good for its intended purpose as a bayonet but I wanted a sharp 25 degree angle. The metal is a very tough high carbon steel so it took me 3 sessions to get the 25 degrees blade sides. The weight of the knife now slices typing paper and shaves with ease. I hacked some vegetation and the knife is still razor sharp. The sheath is also well designed and can be carried many ways. I teach self-defense, hunting, survival and firearms so I believe the OKC3S might be the perfect knife for this aspect. I also ordered an expensive lamp but it popped when I first used it. The KC sent me a mailing label to return it immediately. I went ahead and ordered a Oight M10 with the tact kit to steer clear from old fashioned Iri lamps. Excellent customer service!
