much like the marines themselves... infantry at least, poke, poke. The Ka-bars are tough as hell. the blade will put up with anything you can throw at it, and soldiers throw as much shit at a knife as anyone you can imagine, not so much because of necessity like you would imagine, but more out of sheer boredom. I've seen it all, and every 4th guy has a ka-bar... in 12 years of this foolishness, I've never seen one fail under some really stupid conditions. I have seen a handle bend after being thrown at a wall somewhere in the neighbourhood of 100 times, but it was still usable and hardly the worse for wear after we bent it back with a vice... it's not my favorite knife, but I love them, and I would bet my life on one if that's all I had.
