Resulting from Japanese mastery and know-how, Shirogami 2 is a very high-carbon steel, of impressive purity.
An excellent sharpness, and an easy-to-maintain cutting edge.
Manufactured by Yasugi Specialty Steel, a division of Hitachi Metals, one of the references for Japanese engineering steels, Shirogami 2 is also known as "White Paper Steel", in reference to the colour of the paper that wrapped it, thus differentiated it from other steels. It is one of the most commonly used steels in the manufacture of Japanese knives, its very high carbon content and low impurities guarantee a sharp edge that is as fine as it is effective. It is suitable for the manufacture of knives, straight-razors or even wood chisels.
How to work this exceptional steel shade ?
The Shirogami 2 is a steel that can be forged to make a homogeneous blade with beautiful Hamon (tempering lines). It can also be used as the core in a San Mai blade to give it more ductility. Because of its low content of alloying elements, the forging, normalization and hardening temperatures must be absolutely controlled in order not to obtain too large a grain and a brittle edge.
Quenching must be done with very rapid cooling, in water or accelerated oil.
