I also carry a Leatherman Wave - wherever I'm either on the boat - or going ashore by dink, can't remember the number of times having a folding tool kit on my belt has been invaluable. My last Leatherman however, was a fingernail breaker - blades and tools eventually became very difficult to retract, even with constant oiling. The Wave has clever quick-release tool levers and one-handed knife blade tabs, a great all-in-one tool for sailors.
