The AlumiCutter is made from the highest quality aluminum for ultra-smooth edges and a solid feel without flexibility. The anodized finish gives it a satin-like feel while the photo-anodized calibrations are resistant to cleaners and will not rub off in the face of continuous use. The AlumiCutter is made for safe use with a razor knife or rotary blade. After use with determining measurements, the AlumiCutter can also be used as a cutting edge without changing tools. The raised edge and finger groove will protect fingers and the non-slip backing keeps it positioned with just a touch while the surface will not nick or catch. This silver AlumiCutter is 12" long.
