Gyokucho is the premier Japanese manufacturer of high quality saws with a reputation for reliability and good performance at a modest price. We use a method called impulse hardening to increase the durability of the tooth tips. The cutting edge is heated for 0.003 to 0.005 seconds by applying an electrical current at super high-frequency of 27.12Mhz, instantly hardening the surface of the steel while maintaining the flexibility inside. As a result, the saw’s wear resistance increases. The surface hardness of the blade is approximately from Hv 900 to 1268. The hardened saw tooth is much harder than sharpening files so the blade cannot be sharpened and needs to be replaced once it is dull. All products have a name, blade thickness,
