Alumicutters are a lightweight, but strong 2-in-one tool that allows one to measure then cut along the smooth raised edge that protects fingers. When fingers are in the groove, the blade has a barrier that prevents injury. There is also a non-slip backing made of neoprene to keep the Alumicutter in place. Measurement markings are created with a photo anodizing process that prevents them from being rubbed off. Made of extruded aluminum, it also makes a great inking edge.
