leatherman was the first and is the best. when i was a paratrooper we used them for EVERYTHING! this included opening our meals, to modifing our harnesses, to rigging explosives. since then they have introduced new models with more tools and some have a locking mechanism. but i havent had the heart to buy a new one; cause the old one is still on my side and is the handiest tool i have ever had. i will add that, any multi-purpose tool you have (be it gerber, schrade, leatherman,etc) is better than not having one. :agree:
