Embracing a rapid rise in popularity for his unique designs and committment to striving for perfection, Shunsuke Manaka is the man behind Kisuke knives. From the sketchbook to the kitchen, he is the sole craftsman behind the entire knifemaking process.

Shunsuke engineers these knives using a process known as Warikomi, whereby a glowing hot piece of steel is split, and the core steel is wedged in and forged together. The split steel becomes the outer layers, and the core steel is exposed at the edge. This process produces a stronger, tougher more durable blade.

Often not quite as high in carbon content, stainless steels have added chromium which acts as a protecting element to oxidizing agents such as acidic foods and water. Generally speaking, when a steel has 12% or above in Chromium content, it is regarded as a stainless steel.

They can be hardened to about HRC 60, and as such a sharp edge will not last quite as long as their carbon steel counterparts. The main stainless steels used by Japanese blacksmiths are VG-10 and AUS10, and Ginsan.
