I'm pleased with my Gerber Guardian for the most part. It is very sharp. The assisted opening doesn't work as well as I thought it should. The blade sometimes doesn't get opened all the way. Today this happened to me. I saw the blade was almost open so without thinking I used my thumb. That was a mistake. The knife cuts pretty quickly. One other thing is on the top part of the blade where the word Guardian is, the part of the blade that stays out when the knife is closed, black has rubbed most of the way off. I like the knife, I just hope it loosens up some.
