I broke the tip clean off, about 1" worth, of a Gerber Mk2 survival knife, back in 1982 in Germany, in the US Army. I threw it. I thought i missed, but i didn't. It stuck tip first but broke off in the tree. I dug it out, took it back to the PX the same day i bought it & they replaced it. I told them exactly what happened. I was surprised they replaced it. I have not thrown it or any other knife since.
