A case for disposing surgical blades includes an integral portion for removing the blade from a handle. The conventional blade has a key slot for receiving a inserted portion on the handle, which slides in the slot and passes through a wider portion of the slot permitting the blade to be removed from the inserted portion and handle. The blade has an edge at the rear of the slot for engaging a rear face of the inserted portion. Retaining members on the bottom wall of the case hold removed blades. The blade removing portion has a guide integral with the case for guiding the handle and its associated blade therethrough. The guide includes a slot deeper than the handle for receiving the handle and for permitting the handle to move downward. The guide also includes a shoulder positionable under the blade for supporting the rear of the blade. When the handle moves downward in the slot, the inserted portion pulls the central portion of the blade down causing it to bow on the shoulder and the forward portion of the case releasing the rear edge of the between the blade slot and the handle and permitting the slot of the blade to slide on the inserted portion. The guide also has a stop integral with the case rearward of the shoulder and above the top of the blade prior to bowing the blade for engaging the rear of the blade and for stopping rearward motion of the blade when it is bowed so that the inserted portion moves in the slot to a wider portion of the slot thereby disengaging the blade from the handle. An abutment forward of the guide and integral with the case positioned over the forward portion of the blade and a guard over the rear of the blade prevents the forward and rear portions of the blade from snapping off the case when the blade is disengaged from the inserted portion.
