Abstract
An insertable tooth for use in a slasher for paper pulp manufacture is disclosed to have a flat elongated plate of steel of even thickness having a rounded base and substantially parallel leading and following edges with a V-shaped groove extending along a lower major portion of the leading and following edges. The tooth also has a planar top angularly extending from a lower point on the following edge toward a higher point near the leading edge. A blade of a material having a hardness of at least 9 MOHS is inserted in a notch at the high point of the leading edge. The blade is in the form of a cubic trapezoid, the base of which is arranged essentially flush with the leading edge. The width of the base of the blade is greater than the thickness of the plate of steel forming the tooth. The sides of the blade are relieved from the base while the upper surface of the blade is arranged nearly coplanarly with or slightly above the planar top of the tooth.
