Shaping tool

Abstract

The present invention relates to a rotating shaping tool ( 1 ) designed to treat a surface of body extremities of mammals, in particular the nails or the skin of humans, which tool comprises an elongated shaft ( 2 ), one end ( 3 ) of which shaft can be clamped and the other end of which shaft has an operative section ( 4 ) with a rotationally symmetrical operative zone ( 5 ) which shapes the surface while abrasively removing parts of the surface and which projects beyond a shaft diameter, with the operative zone ( 5 ) on the end opposite to the shaft end ( 3 ) that is to be clamped being bounded by a rounded part ( 6 ) having a domelike structure ( 7 ) without the surface-shaping function that is inherent in the operative zone ( 5 ).

1 . A rotating shaping tool designed to treat a surface of body extremities of mammals, in particular the nails or the skin of humans, which tool comprises an elongated shaft, one end of which can be clamped and the other end of which shaft has an operative section with a rotationally symmetrical operative zone which shapes the surface while abrasively removing parts of the surface and which projects beyond a shaft diameter, characterized in that the operative zone on the end opposite to the shaft end that is to be clamped is bounded by a rounded part having a domelike structure without the surface-shaping function that is inherent in the operative zone. 
   
   
       2 . The shaping tool as in  claim 1 , wherein the domelike structure is smooth, preferably polished. 
   
   
       3 . The shaping tool as in  claim 1 , wherein the domelike structure is a fusion-bonded component of the operative section, with the operative section being made at least substantially completely of a hard metal. 
   
   
       4 . The shaping tool as in  claim 1 , wherein the domelike structure is rotationally symmetrical. 
   
   
       5 . The shaping tool as in  claim 1 , wherein a surface of the domelike structure transitions steplessly into a surface of the operative zone. 
   
   
       6 . The shaping tool as in  claim 1 , wherein the operative zone comprises at least one cutting section. 
   
   
       7 . The shaping tool as in  claim 1  wherein the operative section is made of steel and that the operative zone ( 5 ) is formed by a coating containing an abrasive material.
