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.

Mizuyaki
There are two types of hardening methods for honyaki knives: Mizuyaki (water quenching) and Aburayaki (oil quenching). Mizuyaki prioritizes sharpness and allows for higher hardness of the steel, maximizing performance, making it the best method for honyaki knives. Additionally, mizuyaki is significantly more difficult to execute compared to aburayaki.

The Origin of Craftsmanship
-
Once you experience its edge, you'll be captivated forever—this is why Sakai's forged cutlery continues its legacy.
-
When someone first holds a Sakai knife, they often pause—there's a moment of recognition when they feel something different, something special. It's not just about sharpness; it's about experiencing centuries of refined craftsmanship in your hand. Each blade tells a story of tradition, of countless hours perfecting every detail, of generations of artisans who dedicated their lives to this craft.
-
What keeps our tradition alive isn't just history or technique—it's the moment when a chef makes their first cut with our knife. That instant of revelation, when they understand why we've preserved these methods for so long. We see it in their eyes: the realization that they're holding something extraordinary, something that will transform their daily cooking experience.
-
This is why our craft has endured for centuries. Not because we cling to tradition for tradition's sake, but because the quality of our work speaks for itself in every kitchen, with every cut. Once you've experienced a truly exceptional blade, there's no going back—and that's how our legacy continues, one knife, one user at a time.
-
The true testament to our craft isn't in the telling, but in the using. That's why we say: try it once, and you'll understand why Sakai's blade-making tradition has survived for centuries, and why it will continue for generations to come.
