Description: |
| This invention, sold as the "Wilkro" brand rabbeting plane, used disposable single-edge razor blade as the cutter, an idea that generated lots of Father's Day and Christmas gifts. These planes are typically found in as-new condition, which says volumes about how well they worked in practice. See also patent 2,289,504. |
