This trench knife features a double edged blade although at this point it is no longer sharp, .191" blade stock and 1" blade depth, hidden/takedown tang construction. The handle his made of brass and has a hammer finish. It is stamped USMC, but it looks like the hammer finish might have been added later and it looks like there is some other letters under the hammer finish, but I cannot make them out enough to know what it says. Has patina, oxidation and pitting, scratches, etc. still a cool piece though.
