Abstract
A utility knife has a handle providing a cavity and an opening at one end, and a slide seated in the cavity for sliding movement relative to the opening. Supported on the slide is a knife blade which moves therewith between a position within the cavity and a position projecting outwardly of the opening. The blade has a cutting edge extending along its lower edge, and the slide has a side wall against which the blade is disposed and a base wall upon which a portion of the cutting edge is disposed. The slide has a cam portion configured to produce a horizontal force component on the cutting edge portion of the blade when the cutting edge cuts into the base wall as a result of the cutting force applied by the user on the outwardly projecting blade.
