Description: |
References improvements on the Jackson Gorham patent, 14863, of 12 MAY 1856. Shoulder strips are riveted directly to the blade instead of the handle to ensure squareness is maintained. A sharp projection occurs at the beginning of the rule for reference and an awl is provided in the handle for marking. |
