The Wonder Saw is a Japanese double-toothed saw designed to offer a fast, stable and deviation-free cut , even in demanding woods.
Thanks to a four-opening design , the blade benefits from optimal balance , greatly reducing vibration and fatigue.

The progressive tension of the blade – softer in the center and firmer at the base – minimizes the risk of deviation during cutting. Resistance in the wood is reduced, allowing for a light and precise cut .

The teeth are made by Nakaya's very high precision automatic sharpening machines , then each blade is straightened manually by master craftsmen in Echigo , guaranteeing perfect straightness.

The longitudinal teeth are optimized for straight, transverse and angled cuts, while the transverse teeth benefit from pulse heat treatment for extended cutting time .
