This invention is a surgical scalpel (10) having a retractable sleeve (70). An elongated handle (50) with a contoured grip portion is releasably attached to a blade holder (20) securing a surgical blade (12). The blade holder (20) is secured to the handle (50) by a hook (32) and groove assembly and a male to female connection. The sleeve (70) slides between an extended position and a retracted position on the handle (50) and blade holder (20). The extended position of the sleeve (70) covers the blade (12) thereby protecting operating room personnel. An arch (74) on the sleeve contacts the hook (32) and disengages the hook (32) out of the groove to facilitate removal of the blade holder.
