Our Nagaoke Professional Grade Saw has a blade length of 11½˝ and an over all length of 29˝; Cross-cut teeth are 10 tpi and Rip:teeth are 5 tpi. The master blacksmith forges our Professional Grade Noko Giri from the best quality Japanese "white" steel carefully milled by hand for correct thickness. Each blade is individually heat treated and hardened to 54-56 on the Rockwell C scale. They are then straightened and tensioned by hand. After the teeth are cut, they are given a special finish sharpening (hon metate). The rattan wrapped handle gives the user a secure grip.
