ABSTRACT:
An improved cutter knife for wood chip and flake producing apparatus includes shallow grooves in either the heel face or the gullet face of the knife intersecting the cutting edge and extending away from the cutting edge. The depth of the grooves is less than the depth of cut of the knife, and the grooves and corners formed by the grooves with the cutting edge provide an aggressive serrated cutting edge which penetrates into the wood and remains sharp longer than conventional cutting edges. Also disclosed is a novel wood flake material in which flake members have a larger area of exposured grain than of exposed side grain, thereby providing a short fiber length flake which can absorb moisture quickly by means of the exposed end grains, and can also dry quickly. The flake material is particularly useful as a bedding material for animals.
