I have a collection of dull knives that are in my gear archives. A dull knife is about as useless as teets on a boar hog. (a saying I've heard alot living in the south)
I make sure my little Gerber frame knife is sharp after each use. I usually punish a knife by using it for more than it's intended use like cutting metal, prying stuff apart etc. When it breaks, which I've done several times, I'll get another. I was using my Gerber multi tool once to bore a hole in a heavy rubbermaid plastic product and snaped the blade at the thumb hole. I sent it to Gerber and they replaced the blade and put it in a new sheath. No Charge. <img src="/forums/images/graemlins/smile.gif" alt="" />
