With Shun Nagare, kai has created another innovative masterpiece of Japanese blacksmithing. The sophisticated design, the special properties of the materials used and a technically complex production process mean that this series of knives belongs to the absolute luxury class. On the highly polished blades, an ornately decorated, radial pattern of Damascus layers is visible. This effect, combined with the mottled grey-black handle, gives the knife an impressive overall appearance. The blades of the series consist of two different types of steel, which are bonded to a 72-layered piece of Damascus steel. The complex layering of the two types of steel results in a blade with exceptionally sustainable cutting power.
