  • Cutting/rasping combination tool
    Patent number: 5519908
    Abstract: The present invention provides a combination tool (21) having a knife blade (39), a rasping blade (33) and a knife blade sharpener (47) combined into a single handle member (23). Preferably, the knife blade (39) is extendable and retractable from and into the handle member (23), respectively. In the preferred embodiment, the knife blade sharpener (47) is biased upward against the knife blade (39) but fixed longitudinally. Accordingly, the knife blade sharpener (47) abrasively contacts the knife blade (39) thereby removing debris from the knife blades (39) and maintaining the knife blade (39) in a sharpened configuration. The rasping blade (33) is preferably positioned in a rasping blade housing (29) secured to the handle member (23) opposite the knife blade (39) and the knife blade sharpener (47).
