An adjustable safety utility knife includes an elongated ergonomically shaped handle formed of two elongate shell members each having a peripheral edge and an outer generally convex surface and an inner generally concave surface. The shell members are fastened at the peripheral edges along a vertical parting plane to form an elongated internal cavity. The handle defines a front end, a back end and an intermediate portion suitable for being gripped by a user and also defining top and bottom surfaces extending along opposite sides of the shell members along the peripheral edges. The handle has a slot-like aperture at the front end substantially aligned with the parting plane and dimensioned for passage of a flat cutting blade therethrough. A guide element within the elongated cavity guides the cutting blade between a first position for safely storing the blade fully inside the cavity and a second position for selectively extending the blade beyond the aperture to expose at least a portion thereof. A manually operated button is arranged on the top surface and coupled to the guide element for selectively moving the blade between the first and second positions. The guide element includes a carriage within the elongated internal cavity for supporting a flat cutting blade and guide elements on at least one of the inner generally concave surfaces for guiding the carriage and cutting blade carried thereby between the first and second positions. The carriage includes a locking element for normally locking a cutting blade mounted thereon to substantially fix the cutting blade against relative longitudinal movements between the cutting blade and carriage. The locking element includes an unlocking element the actuation of which releases the cutting blade to permit relative longitudinal movements between the cutting blade and the carriage. A blade release element on one of the shell members actuates the unlocking element when manual force is applied thereto, whereby application of a force on the release element releases the cutting blade and enables it to be withdrawn through the front end aperture.

A control box in the second leg communicating with the opening. A control block mounted within the control box. The control block having teeth extending therefrom which face the threads in the threaded bolt. A control mechanism is provided for moving the control block from a position in which its teeth engage and mesh with the threads on the threaded bolt to a position in which its teeth are disengaged from the threads on the threaded bolt.
