Description We developed this new line of Kazan knives with a knifemaker in Niigata, Japan, using SLD steel. SLD steel was designed as a cutting steel and is known for its strength, toughness and excellent edge retention. Kazan SLD has an HRC of 60 - 62 and has the edge retention of a carbon steel knife as a stainless knife. Kazan SLD features a beautiful cross hatch pattern and hand fitted walnut wa-handles and each knife is finished on a series of stones for maximum sharpness out of the box. Kazan is made exclusively for Chubo. Why we love them: Carbon steel performance in a stainless knife at a reasonable price.
