Outstanding

I purchased this knife because, why have a bayonet lug on your AR if you have no bayonet? The only critique I have is that the retention spring (I don’t know if that is actually what it is called?) that holds the blade securely in the sheath has no protective coating on it, so the first time you put the knife in the sheath it immediately scratches the black coating on the blade all to hell. It seems like a very easy/cheap fix, just coat the spring in some type of plastic or something? It’s not just a cosmetic problem, I imagine over time I will have to take extra precautions to prevent rust in those scratched/exposed areas?

Worthy of the USMC stamp!

I've owned this OKC 3S for several years now and use it as my primary utility, hunting, camping, and hiking knife and it stays my truck always. I've put this knife through some incredible use over the years and it has never failed me. The blade is incredibly strong and it holds a sharp edge very very well. I would recommend this tool to anyone...and it is very worthy of carrying the USMC stamp on the blade. Semper Fi!

Great product

Granted anything can be destroyed but these knives will go through hell. The military tested them by placing a sheet of aircraft grade aluminum around a punching bag then over that a Kevlar vest. It went through through the bag. They are a full tank what feels like a tool strength blade. I recommend a good heavy duty paint to protect the blade as the phosphate coating comes off easily. It is carbon steel which is a good thing but carbon steel is succeptible to rust thus the pain. I used gorilla glue duck tape around the sheeth spring to protect the finish. Absolutely love the sheeth
