    摘要： A polyhedral knife that in side profile resembles a gull wing is configured for being securely retained in a clamping assembly defined by a clamp and a holder, wherein the knife is retained between the clamp and the holder. The knife has a central portion between opposite wing portions. The knife is rectangular in shape and has a central, upwardly extending semi-circular upper ridge that extends across the knife on the upper surface and the upper ridge defines a locator that is retained in a cooperatively shaped groove in the clamp. The lower surface of the knife is defined by a central locator ridge and concave surfaces on opposite sides of the locator. The clamp and the holder have cooperatively shaped, angled and radiused surfaces to mate with facing surfaces of the knife.

    摘要： A cutter includes a first end configured to engage an object along a dominant force vector, a second end opposite the first end, a first side, and a second side opposite the first side. The cutter further includes an outer side, an inner side, and an aperture extending from the outer side to the inner side along a fastener axis that is substantially perpendicular to the dominant force vector. The cutter also includes a cutter tip on the first end and having a first cutting edge, a second cutting edge, and a third cutting edge, the cutting edges defining therebetween a cutting face. The cutting face defines a cutting swath having a width between the first cutting edge and the second cutting edge as the cutter rotates with the apparatus. No portion of the first side or the second side extends outside the width of the cutting swath.

    摘要： A system and method are provided for producing wood curls with reliable consistency and resiliency. Moisture content of wood blocks is determined and a plurality of cutting knives are installed on a disc of a curling machine and set to extend about 0.012 inches from the face of the disc. The wood blocks are fed through the curling machine and the feed rate is set based on the moisture content of the blocks and the sharpness of the cutting knives and readjusted based on the resiliency of previously cut curls in order to produce wood curls of a desired resilience.
