Abstract: A knife is provided that includes a replaceable blade element. The knife employs a blade carrier that is fixedly interconnected to or foldable with respect to a handle. The blade carrier selectively receives the replaceable blade element that is locked into the blade carrier by way of a hook and movable pin combination. The replaceable blade element is designed to be inserted within the blade carrier quickly, easily, and safely.

Abstract: A utility knife with a lockable blade is provided. The blade is selectively extended from a housing with a sliding mechanism. The blade is interconnected to a blade carrier that includes a portion configured to lock the blade in a deployed configuration. The blade carrier includes a deflectable portion that is selectively biased by the release button to unlock the blade from the deployed state. Spring force associated with a biasing member interconnected to the blade carrier draws the blade into the housing when the release button is dispersed.

Abstract: A bracelet or flexible band comprised of a flexible member that on one end is interconnected to a knife and on another end, is connected to a sheath that selectively receives the knife in the locking fashion. When needed, the knife is rotated within the sheath to facilitate release thereof from a lock that is integral with the sheath. Once removed from the sheath, the knife can be used for self-defense, cutting rope or cord in an emergency situation, or for general utility cutting tasks.
