<p>A method is disclosed for marking a tool. The method includes the steps of forming a tool, making an indented mark in the tool, hardening the tool, coloring the tool to provide a color layer on the tool in and near the indented mark, clearing the tool of redundant colorant that overflows from the indented mark, black dying the tool to provide a black-died layer on the tool except the indented mark, and providing a transparent layer on the protection layer except the mark. The thickness of the transparent layer is larger than the thickness of the mark.</p> |
