Manufacturer Part Number (MPN) : C133PAerodynamically the bumble bee shouldn't be able to fly but someone forgot to tell the bee. The flight of the bumble bee defies both nature and one’s expectations that something that small can perform such a grand maneuver. Like bumblebees, Spyderco Bugs perform unexpectedly. The Bug, not much larger than a bee, is our latest addition. Last year Spyderco started offering SLIPITS which are non-locking slip-joint knives. They have no locking mechanism holding the blade open, relying instead on resistant pressure at the pivot area when the blade is extended and being used. Bugs are part of the SLIPIT group. The flat ground blade is 3Cr13 stainless steel available with a PlainEdge. The Bug’s handle offers a flat surface for a small amount of engraving or embellishment and can be customized for use as jewelry or a gift item. Positioned on the end of the handle is a lanyard hole large enough to thread with a chain and be worn around the neck or slipped onto a key chain. The Bug is the smallest folder in our lineup.
