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.
