Description: |
| This is a simple tool to mark a butt mortise. The tools is positioned in place on the door, and the two blades struck with a hammer. This will not only mark the sides of the mortise, but hold the tool in place to allow the attached fence to be used to guide a chisel to cut the mortise.
It is very similar in concept to the D.S. Humphrey patent (#1,008,826 - 11/14/1911), but adds cutting edges for the sides of the mortise.
This tool was produced from 1930-1957 by Stanley, but it apparently never caught on with carpenters. The tool is fairly rare today. |
