How Cooling Magic Transforms Metal

How Cooling Magic Transforms Metal

Metal is like a living entity that changes with temperature. When heated, its molecules spread out; when rapidly cooled, they compress tightly. This process determines a knife's strength and sharpness.

The Origin of Craftsmanship

  • The Essence of Knife Making: Crafting a Story Through Material and Shape

  • Knife making is not just a craft; it’s the creation of a “story” by engaging with materials and giving them shape. Each piece of steel is hammered, heated, and shaped, transforming from mere material into a tool that fits the hand of its user. The moment when the steel takes form in my hands, as if it’s being infused with life, is the most rewarding part of the process.

  • That’s why I don’t just create knives that are sharp; I craft the “perfect strike” for the user. The story that unfolds during this process is the true value for me.
