The name "Kotetsu" (armored steel) comes from a warship called a "Koutetsukan," which is completely covered in armor. In Japan, it refers to a real warship also known as the "Tokan."
The design of the "Koutetsu" knife is the result of pursuing everything desired in a knife. It wasn't originally created with the image of a "Koutetsukan" (armored steel warship). Its shape distributes pressure evenly from the base to the tip of the blade, allowing the desired movement to be transmitted to the tip of the blade, the feeling of placing your index finger on the spine, and a comfortable feeling when holding the handle.
After repeated adjustments, this shape was finally arrived at, reflecting the desired shape for a knife. Try out the sharpness of the "Koutetsu" knife, which can easily cut through paper and even tough raw carrots.
