Rotary Grinding Wheel For Shaping And Sharpening Saw Blade Teeth

Abstract

An apparatus that is meant to facilitate the sharpening of many saw teeth quickly. The unique grinding wheel shapes blade teeth by grinding in a crisscross fashion. The apparatus renews worn or damaged saw blade teeth and is able to shape new sharpened teeth on saw blades with no teeth.
