My dad passed away two years ago this month. I miss him dearly, but dang he had a lot of stuff, and none of it was organized, at least not in any way that I could determine. I'm sure he knew right where everything was . At any rate, while going through a box I found in the attic, I came across this old USMC Ka-Bar. Looks like he broke the tip prying something, and then just re-sharpened it so the end resembles a small chisel. I'm pondering how best to fix that. Sheath and handle had some sort of mold growing on them. Cleaned that up and it's lookin better. He cut the rear part of the guard off, but it was still pretty rough, so I filed it smooth and polished it a bit with my Dremel. I'll touch it up with cold blue one of these days. It looks like the blade was either blued or parkerized, and that might be a clue to the thing's age, since I don't believe Ka-Bar does this anymore. Are there any other clues to how old it might be? There's no serial number that I can find. Here's some pics.
