Honyaki
Honyaki knives are manufactured using a different method from general knives. Unlike kasumi knives, honyaki knives lack a soft iron core, making them more susceptible to shocks and very prone to cracking during the hardening process, as there is no escape for the damage. To mitigate this and make the blade less likely to break, a process called "tsuchioki" is performed. Tsuchioki involves applying a mud-like clay to areas that should not be hardened before the hardening process. This ensures that the steel on the spine remains tough and flexible, preventing the blade from cracking. The shape of the tsuchioki application creates wave patterns or Mount Fuji patterns on the blade. Due to the complexity of the hardening process, only a few craftsmen in Sakai (or nationwide) can produce honyaki (mizuyaki) knives.
