metal sanding devices

Abstract

A multi-tasking disk which in one form is used primarily with a powered hand tool to remove measured amounts of material from the surface of a work piece, and, in another form, serving as a buffing tool for removing minute amounts of skin from feet, elbows and the like on a human, or removal of like minute amounts from vegetables.

       18 . The omnidirectional abrader element of  claim 13 , wherein said abrader element is formed by a photo chemical etching process. 
   
   
       19 . An omnidirectional metallic sanding device for removal of material from a work piece; said sanding device having at least one abrader element, said abrader element being formed by first creating at least one opening in said disk; said opening have an interior wall;
 thereafter sharpening edges about at least a portion of said interior wall; and offsetting said sharpened edges from the plane of said disk such that said sharpened edges cause removal of material from the workpiece irrespective of the direction of movement of said abrader element.   
   
   
       20 . The omnidirectional metallic sanding device of  claim 19 , wherein projections are formed along said interior wall of said opening; said projections having sharpened edges, said sharpened edges being beveled. 
   
   
       21 . The omnidirectional metallic sanding device of  claim 19 , wherein said opening is formed and sharpening of said interior wall of said opening is accomplished in a single step.
