Yokobiki Noko Giri have a single set of teeth and are taper ground to prevent binding in deep cuts. These saws are useful for those cuts which require the blade to be laid flat on the work. The 7«" to 9«" sizes are best suited for furniture and fine work.The large sizes are used for carpentry and large work. This Professional Grade has a 9-1/2" Blade length with a 24" Overall length and 16 tpi. The master blacksmith forges these Noko Giri from the best quality "white steel" carefully milled by hand. Each blade is individually heat treated and hardened to 54o 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.
