This is one of the world famous Chantry Knife Sharpeners. The Chantry Sharpeners are well known for their superior design and functionality. This award winning Modern Chantry features a sleek design with a long handle for easy gripping. This is not a knife grinder, so will not damage the knife. At the heart of the machines are two small butchers' steels, the same hardness, temper and cut as a professional steel. The steels are pre-set at the optimum edge angle and are spring loaded so as not to damage the knife. Just run any knife blade between the steels four or five times and your knife is sharpened!
