Ni-Mai Knives

While Ni-Mai lamination is similar to San Mai and Warikomi techniques, the main difference is that the blade has a layer of soft steel on only one side (usually the back). This structure is created as follows:

Core Steel (Hagane) - Cutting Edge:
It is made from high-carbon hard steel. Shirogami (White Steel) or Aogami (Blue Steel) is commonly used. It has an ideal structure for superior sharpness and precise cuts.

Outer Layer (Jigane) - Back Section:
A softer steel or stainless steel is used.
It reduces the fragility of the blade, making it more durable.
It improves stability and cutting control in single-edged blades.
In this design, the cutting edge is made entirely of hard core steel, with only the back of the blade covered in mild steel. This ensures excellent sharpness and stability.
