PURPOSE:To obtain an abrasive surface capable of maintaining a razor under a condition, in which sharpness is provided and micro R edge, undeformable for beard, is formed, by utilizing actions of a cloth abrasive surface with elasticity and that almost without elasticity. CONSTITUTION:Considering sharpness for an abrasive surface sharpening a razor edge, both of a cloth abrasive surface 6, having elasticity, and cloth abrasive surface 5, almost not having elasticity, are simultaneously used, and balance of use is suitably changed to keep a condition of ideal micro R edge. In short, a razor can be used while adjusting the edge. An edge angle of the razor possessed by a barber for business use is not fixed variously in 16-24 deg.. Considering an edge angle of the razor, the both abrasive surfaces are simultaneously used, or a change of proportion in use of the both abrasive surfaces is obtained to form a condition of ideal micro R edge, and this condition can be maintained. |
