Alumicolor AlumiCutters measure and then use the cutting edge without changing tools. AlumiCutter's raised edge and finger groove protect fingers while cutting. Use the AlumiCutter with a hobby for safe cutting! The neoprene recessed non-slip backing keeps the AlumiCutter positioned with just a light touch. Made from extruded aluminum with markings done using Alumicolor's photo anodizing process is also an ideal raised inking edge.
