When you hold a Spyderco knife in your hand you know you are holding quality. SPYDERCO is backed by more than 30 years of research and development to find the right steels and handle materials. All Spyderco knives have been ergonomically designed to open easily and fit comfortably in the hand while cutting. And each pocketknife will hang out in your pocket until you need it. Almost all Spyderco folding knife models feature the thumb hole pull for easy, one handed opening. Most have a pocket/belt clip for convenient carrying.
