Unique handle design. Patent pending unique handle to blade design, combined with the patented universal triple ground teeth, completely eliminates binding and cuts 3 times faster than traditional hand saw through virtually any material. The patented universal tooth grind rapidly removes material, delivering the speed that is expected from a coarse cutting saw with the fine finish of a fine cutting saw in most standard building materials. The comfort handle is constructed of a high density resin and molded into an ergonomic grip. This handle is lighter than traditional handsaws, resulting in less hand fatigue. The blade profile has a tapered pitch nose for improved clearance through materials and stability with every stroke. The thick body saw blade is .85mm thick with a water based lacquer coating, delivering a faster, more controlled cut. The 90 and the 45 angle markings are fast and convenient features, providing a reliable straight edge for quickly marking work surfaces.
