In 1847 Therry des Estwaux invented the pencil sharpener. The design since hasn’t change much. It basically consists of a razor blade fastened to a cone. 8 (ATE) is a double – bladed stainless steel pencil sharpener which effectively sharpens both thick and thin pencils. One inserts the pencil into one of the holes, and twists the pencil while holding the sharpener steady. The inbuilt blade shaves the wood and also prevents the tip from breaking.  A satin finish that looks wonderful even rolled over on its side.
