Types of Japanese Kitchen Knives
There are two classes of traditional Japanese knives forging methods: Honyaki and Kasumi. The class is based on the method and material used in forging the knife. Honyaki are true-forged knives, made entirely of one material, high-carbon steel. Kasumi are made from two materials, like samurai swords of old: high-carbon steel and soft iron forged together (known as san mai blades), with the steel forming the blade's edge and the iron forming the blade's body and spine. Honyaki and Kasumi knives can be forged out of either ao-ko or shiro-ko steel. Based on their kirenaga (duration of sharpness) and hardness, however they are more difficult to use and maintain. Additionally, there are high-grade quality Kasumi knives called Hongasumi and layered steel Kasumi called Damascus which have longer kirenaga.
Originally, all Japanese kitchen knives were made from the same carbon steel as katana. More expensive san mai knives have a similar quality, containing an inner core of hard and brittle carbon steel, with a thick layer of soft and more ductile steel sandwiched around the core so that the hard steel is exposed only at the cutting edge. Nowadays stainless steel is often used for Japanese kitchen knives, and this san mai laminated blade construction is also used in more expensive blades to add corrosion resistance while maintaining strength and durability.
