Master Grade is built with the best materials, parts and technology in the industry. The V-shape manual sharpener is designed only to sharpen one point of the cutting edge without any support, therefore, after around a hundred passes, the cutting edge will start to have an uneven wear and gradually will develop a wavy edge. Master Grade's round discs are built with the top-grade of tungsten with multiple discs to stabilize and guide for balanced sharpening to prevent a wavy edge.
The tungsten discs last 100 times longer than a V shape, certainly the longest life compared to any manual sharpener.
