Steel is the perfect edge for razor straight trimming, your blade slips along the steel with dead on accuracy. The stainless steel edge is low and flat, so your blade won't wobble. We took the best elements of the Safety Ruler and added a wider hold down base and a new non-slip backing that is thinner with a more powerful grip. The tool steel is .069" thick by 1.25" wide, It is joined to the base and protrudes from the side of the ruler. Trim fast. Trim straight. World's best cutter.
