This Craft Sha leather corner cutter is constructed of high-quality steel, with a tempered blade polished to a razor-sharp edge that ensures leather corners are cut neatly with every stroke of a mallet. To achieve accurate and uniform cuts, the blade's elongated ends are intended to line up with the edges of the leather. This tool's handle is welded to the blade and features a nonslip finish for a more comfortable grip while in use.Make the corners of your leather items smooth and professional-looking with this leather punch along with other sizes (each sold separately). To protect the blade from dulling or breaking, always use a cutting board and position it under the leather you're going to cut.Approximate Dimensions & Product Data:• Weight: 129g• Length: 131mm• Width: 64mm• Depth: 45mmAvailable Sizes (each sold separately):• R3 (3mm)• R6 (6mm)• R8 (8mm)• R10 (10mm)(R) is the notation for the radius of the curve the tool cuts.As with all tempered edges, the blade can be strong yet brittle, therefore please ensure the tool is stored away from hard implements or surfaces, avoids sudden impacts and is kept oiled and dry when not in use.
