ABSTRACT:
A knife and apparatus for clamping the knife. The knife has front and back sides that, preferably, both include interlocking features adapted for interlocking engagement with corresponding inner and outer clamping members, to prevent slippage of the knife from the clamping members in orientations wherein the knife rests thereon in the chipping apparatus when the knife is unclamped. Preferably, the interlocking feature of the back side of the knife includes a semi-cylindrical groove, and the interlocking feature of the front side of the knife includes two spaced-apart deflector ridges. Preferably, the interlocking feature of the outer clamping member is a projection having a semi-cylindrical tip portion wherein the semi-cylindrical shape is preferably half-cylindrical, and wherein the projection extends from an inner surface of the outer clamping member sufficiently far that most of the back side of the knife does not make contact therewith.
