This 3 piece set is forged from a high quality (M/V) stainless steel that is very sharp and easy to resaharpen on the KC 100 Water Wheel sharpener. The knives are made by a commercial knife maker in Japan that only supplies large retailers and Department stores in Japan. |Is made by a very modern factory that uses robots and automated processes to achieve exacting standards expected by Japanese consumers and will compare to any Western made resharpenknife at even twice the price. The Tsuchime finish reduces the adhesion of sticky foods by breaking the vacuum between a smooth surface of the blade and the food being cut. Fantastic value. Knives Sizes: Small Deba: 120mm Santoku: 170mm Nakiri: 170mm
