At first I was going to ask about the TL-29 stamping on this Ka-Bar toothpick fish knife. But, then I realized it's actually stamped on the handle T29.
So, i'll go down both roads.
I've always thought that the TL-29 marking was a military related thing, is that so? In the case of this Ka-Bar, does the T29 have anything to do with being military issue or just a model number and coincidence that it's close to the TL-29 marking? I couldn't imagine why the military would issue a fish knife, but then again maybe they didn't. I'm confused! Need more coffee!
