Karin Air-Hardening Steel Calligraphy Knife with Transparent Handle

Air-hardening steel refers to steel that hardens on its own when exposed to air. Sharp and durable steel materials are produced using this method. This method is frequently used in the production of industrial steel materials.

Calligraphy knives, which calligraphers use to sharpen their pens, must also be both sharp and durable. You can comfortably use calligraphy knives made from air-hardening steel for many years.
