I had a Leatherman Pocket Survival Tool for about 5 years and lost it. It served me well, but had some drawbacks like a non locking knife (though the doubled back handle did protect your fingers.
I did like it''s very compact profile and light weight.
I would like to hear what others think of their multis. A friend of mine has a Gerber with a pliers head that slides into place when snapped with one hand. that looks cool and seems usefull. What are you using and how is it?
