These Damascus Pattern Kitchen knives are made by a unique process developed by a master blade maker. Construction of the Jigane begins with bundles of special alloy stainless steel wire which are repeatedly folded together and forge welded by hand. The Hagane, center portion, is forged of high carbon steel alloyed with cobalt. The Hagane is then forge welded between 2 layers of Jigane; showing a beautiful Damascus pattern. These blades are honed to a marvelous razor edge.
