I have:
A Leatherman Wave of uncertain age, which I inherited from my father. It’s got pliers, wire cutter, metric and American rulers, large flat screwdriver, jewelers’ flat and Phillips screwdriver (reversible), scissors, can opener, medium flat and Phillips screwdrivers (reversible), straight blade knife, serrated knife, file with three textures (one on each side and one on the edge), and saw.
A Wenger Swiss army knife, approximately 20-25 years old, with can opener, bottle opener, flat screwdriver, saw, scissors, knife, nail file, Phillips screwdriver, awl, and keychain. It used to have a tweezers and toothpick, too, but the tweezers broke, and the toothpick has gotten permanently wedged into its slot.
A 13-function utility pen, with short and long Xacto blades, small saw blade, small file, Phillips and flat jewelers screwdrivers, nail remover, pick, tweezers, and something called an “ear pick” that I’m afraid to know what it does. Oh, and a ballpoint tip, but that really doesn’t work well.
And yes, I’ve used almost all of the tools, on all three of them.
