Why choose this tool? Many tools on the market have a single function. As a result, users need to purchase multiple tools.After professional design modification, we developed this tool in four styles. You only need to rotate the blade selector on this trimmer to be able to cut straight or wavy edges, cut perforations, or score for folding. It's lightweight, but sturdy due to the design of the intersecting ribs under the cutting edge, and there's a 1cm alignment grid printed on the cutting surface as well as rulers in inches and cm on each end and lines for common cutting angles.
