Japanese saw

 

— many Japanese saws outwardly resemble knives or even spatulas — instead of D-shaped handles, they often use the simplest oblong handles directed along the blade or at a noticeable angle to it, and the blade itself can expand towards the end, resembling an elongated spatula in shape. Another feature common to almost all Japanese saws is the backward curved teeth. Thus, the main working stroke of the saw is towards itself; it is believed that this sawing provides better control over the blade and increases accuracy. The teeth are usually made quite small, coarse-toothed tools are much less common.
