<p>A replaceable cutter tooth for mounting to a saw blade has a concave fro nt cutting surface extending from and between opposite kerf forming linear side edges, and from and between a radially inner curved edge, radially inner when mounted on a s aw blade, and a radially outermost curved cutting edge. A groove extends in the radial direction from the radially inner curved edge to the radially outermost curved edge, generally medially between and substantially parallel to the side edges so as to reduce the surface are a of a front face of the front cutting surface of the tooth for ease of re-sharpening in the field.</ SDOAB></p> |
