Method and System For Tool Wear Indicator

Abstract

A wear indicator on a tool is provided that can be used to determine if the blade or edge of the tool is worn past a predetermined point. It provides for the easy identification of the condition of replacement wear surfaces. The wear indicator or marking may be implemented in many ways that will not interfere or impede in the integrity of the blade or tool. Some examples include laser etching of the mark, a line pressed into the surface of the blade, dimples along a line, a scribe mark, paint, a material located inside of the product that becomes visible when the part to be replaced, or any other suitable way to easily and visually determine the condition of the blade.

1 . A snow plow, comprising:
 a replaceable blade attached to the snow plow: and   a wear indicator on the replaceable blade indicating a level of wear on the blade.   
     
     
         2 . The snow plow of  claim 1 , wherein the wear indicator comprises a laser etching. 
     
     
         3 . The snow plow of  claim 1 , wherein the wear indicator comprises is line pressed into a surface of the replaceable blade. 
     
     
         4 . The snow plow of  claim 1 , wherein the wear indicator comprises dimples along a line on the replaceable blade. 
     
     
         5 . The snow plow of  claim 1 , wherein the wear indicator comprises paint. 
     
     
         6 . The snow plow of  claim 1 , wherein the wear indicator comprises a material that becomes visible upon the level of wear on the blade, 
     
     
         7 . A method of using a replaceable blade on a snow plow, comprising:
 applying a wear indicator to a replaceable blade;   attaching the replaceable blade to the snow plow;   determining whether the wear indicator is visible on the replaceable blade; and   replacing the replaceable blade based on the determination of whether the wear indicator is visible on the replaceable blade.
