The 22 tpi Japanese tooth-pattern blade cuts aggressively (on the pull stroke), but does not mark the surface that it is cutting next to. The thin blade is flexible and can be pressed flush to any surface, yet is rigid enough for good control.
The saw is available with teeth cut on only one edge or in a double-edged style that cuts from either side. Each is about 11-1/2" long with 4-3/4" of blade. These work like a charm.
