The super thin kerf (0.5mm) and high number of teeth per inch (approx. 20) on this saw make it the perfect choice for fine joint making. The shark tooth type teeth are hardened to 52-54 Rockwell. Blade is approx. 11" long. Overall length of saw is approx. 21-1/2". Rattan-wrapped handles. Highly recommended for use with the AngleMag Joint Making System (#67728 ). Japan
