Abstract
A utility knife configured with a retractable cutting blade that is extended and retracted by a blade actuation mechanism. The blade actuation mechanism employs a blade trigger assembly and a blade carriage assembly that are operably connected in variety of configurations. Certain configurations of the blade actuation mechanism utilize a rack-and-pinion arrangement between the blade trigger assembly and the blade carriage assembly, which enables the automatic retraction of the cutting blade as the cutting blade is lifted from the cutting surface.
