What are the advantages of 440C steel?

440C steel from Aichi Steel is a high-carbon Japanese stainless steel: it is much less prone to rust than carbon steel. In addition, its heat treatment (also known as “tempering”) allows KOTAI knives to reach a hardness of HRC 60 ±1 without compromising toughness or impact resistance.

What’s the difference between single-layer steel and Damascus steel?

Damascus steel provides a sharper edge while also protecting the knife from impacts thanks to multiple layers of steel wrapped around a central core. However, this manufacturing method is more expensive and time-consuming compared to a single-layer steel blade, which is still perfectly suitable for home or professional use.
