The Instablade credit card knife is an innovative new idea that provides a light and ultra sharp knife in the shape and size of a credit card. The knife is attached to a hinge that swings out, and the “card” portion turns into the knifes handle. When folded up, the knife includes a locking mechanism to protect you from the blade and a protective sheath to protect the blade from you.
