Made from the highest quality aluminum for ultra smooth edges and a solid feel without flexibility. The anodized finish gives a satin-like feel. The photo-anodized calibrations are resistant to cleaners and will not rub off. 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. The raised edge and finger groove protects your fingers. The non-slip backing keeps it positioned with just a touch while the surface will not nick or catch.
