A self-loading utility knife including an elongate handle having an internal chamber defining an axis and at one end is flat aperture for the passage of an active blade. The flat aperture defines a cutting plane extending through said handle along the axis. A blade-holder is slidably mounted in the chamber for movements in directions along the axis and is adapted to secure a single active blade for movement through the aperture when the blade holder is in the extended position. A blade-holder release button is coupled to the blade holder and is slidingly movable relative to the handle to move blade holder between retracted and extended positions. The handle has a blade compartment which is open to the chamber and can receive a stack of spare blades when a cover to the compartment is opened and blades can be shifted transversely relative to the axis into the chamber. The blade holder is provided with a recess having a depth no greater than the thickness of one blade to allow at least a portion of a single blade to be received in a retaining relationship within the recess to cause an end-most blade in the stack to be received within said recess to follow the movements of the blade holder. A spring biases the blades in the blade compartment inwardly in the direction of the blade holder. A blade releasing disc on the blade holder selectively locks a blade to the blade holder when the blade holder is in the extended position. The blade holder only receives a single blade within the recess. A belt clip s provided on the compartment cover.
