This keyhole saw provides the most striking example of the advantage of cutting on the pull stroke, the traditional cutting action of Japanese saws.
Because the blade is under tension rather than compression on the cutting stroke, it can be much narrower than an ordinary keyhole saw. Very small radius cuts are possible. The teeth need little set because the blade is tapered from tooth to back.
It comes razor sharp with a 12 tpi blade, 8" long; 12-1/2" long overall. The blade is double pinned in a hardwood handle. An excellent saw.
