Sound design is the foundation of TENRYU fs high quality saw blades. To produce blades that give the finest cuts, our designers consider the material that will be cut, the type of machine that will be used for the cut and the desired outcome.TENRYU uses laser on high-end blades to incorporate thin-gap expansion slots. All TENRYU plates are hardened to at least 40 HRC so they can withstand heavy loads and continue working with excellent results. All plates are guaranteed to be flat. TENRYU fs proprietary flattening and surface grinding processes ensure plates that are distortion free and have uniform thickness. The TENRYU grinding process is a painstaking one. Each tooth is perfectly honed. Proprietary cooling methods assist with creating mirror-like finishes on the carbide teeth. This results in reduced micro-chipping along the cutting edge- thus a sharper, keener edge.
