Abstract
A utility knife includes a handle, a blade holder assembly, a pair of resilient blade wiper members, and a spreader. The blade holder assembly is constructed and arranged to hold a blade at a position of use wherein the blade projects through an opening at a front end of the handle. The pair of resilient blade wiper members are biased towards one another and constructed and arranged to remove debris from side surfaces of the blade, which debris would otherwise be brought into an interior space of the handle when the blade is retracted into the front end of the handle through the opening. The spreader is constructed and arranged to spread the resilient blade wiper members apart to facilitate removal of the blade from the handle when the blade is in a blade change position.
