ABSTRACT:
A retractable blade utility knife is formed of a pair of elongated mating handle halves separable along a plane extending longitudinally of the knife and terminating at one end in a blade receiving opening. A blade carrier is mounted between the handle halves for supporting a blade for reciprocation between an exposed and sheathed position. Each of the handle halves is provided with a longitudinal extending slot and the blade carrier is provided with a finger piece extending through one of the slots and a carrier base with an offset extension connected thereto by a necked portion extending through the other of said slots with the necked portion disposed in said slot. The finger piece is threadably received in a threaded dimple on the extension and is rotatable relative thereto to serve the dual function of securing the handle halves together and securing the blade carrier in adjusted position.
