Wood-cutting apparatus with an insertable tooth in which the blade is positioned radially outwardly on a flat, elongated metallic plate and comprises two side edges, each of which: a) extends generally radially (i.e. parallel to a radius of the disc in which the tooth is inserted); and b) is positioned ahead of the plate and other portions of the blade so that the side edges lead the tooth as the disc rotates in a predetermined rotational direction. The cutting edge of the blade extends along the most radially outward extent of a region of the blade connecting the two side edges, the connecting region being positioned rearwardly from those side edges in the rotational direction.
