Saw blade

A saw blade includes a body and a plurality of cutting teeth formed on the body. Each cutting tooth includes a tip at a first end of the cutting tooth, a rake face extending from the tip toward the body, a relief face extending from the tip toward a second end of the cutting tooth and sloping toward the body, and a projection at the second end of the cutting tooth and sloping away from the body. The saw blade also includes a plurality of gullets formed on the body between the plurality of cutting teeth. Each gullet forms an undercut portion between the body and the projection of each cutting tooth.

There is provided a tool blade, comprising a backing strip particles of abrasive material and a binder layer of binding material which binds the abrasive particles along an edge of the backing strip, wherein the edge of the backing strip is pre-formed with teeth, on which the abrasive particles are bound by the binding material. A profiled cutting portion extends beyond the pre-formed teeth. The pre-formed teeth are shaped as generally triangular waves or are flattened at least partially along an upper edge on which the cutting portion is at least partially disposed. A method of making such a blade is also provided.
