Among Japanese knives, it is easy to quenchand the knife made from this material is the mostaffordable.SK (Carbon Tool Steel)…It is a steel material that has less carbon thanNo. 2. Generally, knives made fromNo. 3 arefor home use and knives made from No. 2 andhigher grade steel are for professional use. It has a highertoughness and is softer compared withNo. 2.ShirogamiShirogamiShirogamiShirogamiShirogami(White Paper Steel) No. 3…It is a steel material made from SK (carbon tool steel) byremoving impurities. This steel material is difcult toquench, and the number of artisans who can forgeNo. 2 is decreasing. It is said that it is a steelmaterial with a composition closest to whichis used for making Japanese swords.Tamahagane ShirogamiShirogami(White Paper Steel) No. 2…No. 1 is a steel material made by addingcarbon toNo. 2. It has a lower toughnessand is harder thanNo. 2.
