The small Leatherman Squirt tools include a bottle opener with a screwdriver tip. It's a handy accessory that will prove invaluable when you discover a wild case of micro-brewery beer beneath a maple tree in the forest.
To use the Leatherman bottle opener, hook the small protrusion under the edge of the bottle cap, with the main part of the toop in the middle the cap. Then pry gently. The tip is also a medium-sized screwdriver.
