  • Publication number: 20070204471
    Abstract: A knife system including a handle and a disposable and interchangeable blade sized for kitchen, hunting, or fishing uses. The knife handle grips surround a handle core component. The handle core is shaped to hold a disposable and interchangeable knife blade. A latching arm component resides within the handle core, placing tension on the knife blade as the blade is inserted into the handle. A protrusion and a cutout on the latching arm and the blade engage each other and lock the blade in the handle. A blade release member is actuated against a release spring to force the latching arm to disengage and release the blade. The knife system has the advantages of easy removal, disposal, and replacement of dull, broken, or damaged full-sized knife blades.
