Manufacturer Part Number (MPN) : C137PAerodynamically bumble bees shouldn't be able to fly. Too bad someone forgot to tell the bees that. This knife defies both nature and expectation that something this small performs such a grand maneuver. Like bumblebees, Spyderco Bugs and HoneyBees perform the unexpected. Our smallest folders, they pack a stinging cutting clout in micro-sized SLIPITs. Resistance pressure at the knife's pivot area holds the blade open and extended when cutting. Handles are flat with a small stainless surface ready for you to engrave, embellish or customize as jewelry or a gift item. Handle lanyard-hole accommodates a necklace-chain or keychain.
