  • Self-sharpening utility knife
    Patent number: 6718639
    Abstract: A cutter has a blade housing; a blade carrier; and a blade engaged within the blade carrier. The blade housing receives the blade carrier and blade in sliding engagement along a longitudinal direction for retracting and extending the blade forward of the blade housing. The blade carrier is further movable between an upwardly biased position and a downwardly depressed position within the blade housing against a spring biasing element which urges the blade carrier to the upwardly biased position for locking the blade carrier in one of a plurality of slots for fixing the blade at a selected degree of extension. The blade carrier may be partially depressed to disengage the blade carrier from the slots enabling longitudinal motion and may be fully depressed to engage a cutting edge of the blade with a sharpening stone for honing the blade as the blade carrier moves within the housing.
