Abstract
A method for treating a knife cutting edge with a laser deposition (sintering) process using a composition coating such as a diamond powder or a substance above 5 on the Mohs scale of mineral hardness. The coating providing an abrasion resistant cutting edge and creates a differential hardness on the total cutting edge. The differential hardness extends the cutting ability of the knife through a wear-resistant surface on a treated surface and a faster wear on an untreated surface causing the cutting edge to be self sharpening as the untreated surface wears away.
