The fiat blade portion 5 or extension of the tubular shank is tapered to a straight transverse cutting edge 6, disposed at right angles to the longitudinal plane of the tool-head. The wide flat faces and the narrow side edges of the said flat blade 5 merge into and form direct continuations of the contiguous flat faces of the shank, and the longitudinal bevels 4 at the corners of the latter are also continued into the side edges of the blade.
