Gerber Pro Scout 600
Awesome piece of kit, the second one I have owned. The only reason I have had to buy again is that I lost my original one. Always with me while at work or outdoors / camping. It's tough, compact, rigid and the single handed opening with a flick of a wrist is real useful, when you are already holding on or using the other hand. Virtually indestructable. if used correctly. The truth be known and from experience as I have used these quite a lot, is that the pouch will wear out or the belt you have it attached too way before the tool does.
