Abstract
The utility knife of the present invention has a cutting blade that is extended to any desired length from the knife handle by providing a blade assembly and a blade deployment device supported in an internal cavity within a knife handle. In particular, the blade can be extended any desired distance from the front face of the handle between the full deployed position and the fully retracted position. No additional structure or locking devices are generally required to retain and hold the blade in a predetermined position from a handle opening when it has been deployed by the blade deployment device. Optional aspects of the invention include a blade position arm and indices, a locking collar and an elongated handle that may be made to articulate.
