Zetsaw Kataba for Cross Fine H-225

The manufacturer describes this saw as the finest single edged saw without a spine along the blade back, designed for making deep crosscuts for wood joineries or other precise woodworks.  

The cut is particularly fine and precise and the teeth are impulse-hardened for a long service life.  The overall weight of the saw is just 100g.  The very light handle is made of paulownia wood.
