Spyderco Bug Knife
It's a good thing the Spyderco Bug Knife has a lanyard hole that's large enough for a key ring, because you're going to want it attached to something so it's not so easy to lose. This tiny folder measures 2.875 inches open and just 1.625 closed, with a flat-ground, 1.3-inch 3Cr13 stainless steel blade. The handle is also constructed of stainless steel, has a satin finish, and carries the company logo on the side.
