Abstract

A finger-mounted filing device can include an abrasive surface that can include a plurality of cutting edges in fixed relation. The abrasive surface can be used for grinding a work surface, such as a fingernail of an infant, child, or adult. The abrasive surface can include a finger surface located on an opposing face of the abrasive surface. The finger surface can be shaped to receive an operator's finger. The abrasive surface can be coupled to a finger clamp. The finger clamp can include the finger surface and at least one jaw, such as for griping an operator's finger. The finger surface can include a fingertip insertion stop. The fingertip insertion stop can include a barrier to retain the finger on the finger surface.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A device comprising:
 an abrasive surface, wherein the abrasive surface includes a plurality of cutting edges in fixed relation;   a finger surface on an opposing face of the abrasive surface; and   a finger clamp coupled to the abrasive surface, the finger clamp including the finger surface and a jaw.   
     
     
         2 . The device of  claim 1 , further comprising a fingertip insertion stop located at an end of the finger surface opposite to an aperture end of the finger surface. 
     
     
         3 . The device of  claim 1 , wherein the abrasive surface includes at least one facet. 
     
     
         4 . The device of  claim 3 , wherein at least two facets are aligned at an angle between fifteen degrees to forty-five degrees. 
     
     
         5 . The device of  claim 1 , wherein the jaw includes a cantilevered beam. 
     
     
         6 . The device of  claim 5 , wherein the jaw includes an elongate member, the elongate member aligned between the jaw and the fingertip insertion stop. 
     
     
         7 . The device of  claim 1 , wherein the finger surface has a length of less than five-centimeters. 
     
     
         8 . The device of  claim 1 , wherein the finger surface has a concave shape. 
     
     
         9 . A method comprising:
 forming a plurality of cutting edges on an abrasive surface in fixed relation;   providing a finger surface on an opposing surface of the abrasive surface; and   coupling a finger clamp to the abrasive surface, the finger clamp including the finger surface and a jaw.   
     
     
         10 . The method of  claim 9 , further comprising forming a fingertip insertion stop located at an end of the finger surface opposite to an aperture end of the finger surface. 
     
     
         11 . The method of  claim 9 , further comprising providing at least one facet on the abrasive surface. 
     
     
         12 . The method of  claim 11 , further comprising aligning at least two facets at an angle between fifteen degrees to forty-five degrees. 
     
     
         13 . The method of  claim 9 , further comprising forming a cantilevered beam on the jaw. 
     
     
         14 . The method of  claim 13 , further comprising forming an elongate member on the jaw, the elongate member aligned between the jaw and the fingertip insertion stop. 
     
     
         15 . The method of  claim 9 , further comprising configuring the finger surface to have a length less than five-centimeters. 
     
     
         16 . The method of  claim 9 , further comprising contouring the finger surface to have a concave shape.
