There's nothing better than having all of your hex and torx keys in one simple caddy like a Leatherman. These take the cake. Very rugged, high-impact designing make these virtually indestructible. No more hunting down those keys in the bottom of the tool box. I put these in the side pockets of my wide mouth tool bag for those very occasions. Knowing you have both standard and metric hex and the torx along with it make it a great companion to a folding screwdriver set offered by Craftsman as well. The only complaint I have is that when these ship from the factory, the keys are screwed down SO tight you can barely move them. Guess having a few spare loose keys comes in handy in such an occassion?!?
