Adjustable lower blades guarantee cuts without burrs. Notches as large as 100 x 100mm, in 3 mm mild steel, can be cut in one operation. Gauges are suitable for straight and mitre cutting. The special design of the blades, the point of which first touches the sheet, has the following advantages.
1. The sheet is kept in place and cannot move.
2. When cutting small notches, the handle has to make a small stroke.
