Abstract
A hand knife having a ring-like rotary blade the diameter of which is considerably greater than its axial length rotated by a motor in a handle extending normal to the axis of rotation of the blade. The blade of the knife is rotatably supported in a blade housing that surrounds it and which can be removed together with the blade for sharpening of the blade by merely loosening a pair of threaded fasteners. The knife also has a member in the interior of the blade which guides a part being removed from a product being processed through the central opening of the blade and interferes or restricts the movement of the part with the circular rotation of the blade thereby increasing the efficiency of the cutting operation. The material guiding and restricting member is connected to the knife by the same fasteners which connect the knife housing to the knife handle, may be angularly adjusted within the blade and/or may also be disassembled from the knife without removing the fasteners.
