Prove it. Like what.
Ah, the old you don't use your knives argument. Seems to be a lot of that going around. Not saying this is the case here but what a lot of folks who claim others "don't use their knives" treat their own knives like poop. I use my knives but I take care of them. Just because a knife is on my belt doesn't mean I am going to smash it into things. If it weren't there, that would be my hip, or butt, or wherever I choose to carry it.
I have had this schrade old timer for over 20 years (don't get too excited Boris, this was when schrade was schrade). It has been across the country twice, on more camp outs than I can remember, and even been on my belt a time or two. The green rubber handle has held up fine. I don't know what some folks do with their knives but for me, a person who takes care of their stuff, rubber handles have held up....
