Use the AlumiCutter with a razor knife or rotary blade safely! You can measure and then use the Alumicutter as a cutting edge without changing tools. AlumiCutter's raised edge and finger groove protect your fingers while cutting. The special recessed non-slip backing keeps the AlumiCutter positioned with just a light touch. Extruded anodized, aluminum is an ideal cutting edge because it is an ultra smooth hard surface that will not nick or catch. Available in black & silver. Select models may contain an added steel edge.Price updated 10/10/2021
