This beautiful traditional forged knife is called “Blue Moon”, which is青月“Seigetsu” in Japanese. This is because we felt that the unique Tsuchime (“Hammered pattern”) dimples and dark-colored Kurouchi (“Black forged”) finish of the blade looked just like the cratered surface of the Moon.
The core of the blades is made from Hitachi Blue Steel No.2 Japanese high carbon steel, which is sandwiched between soft stainless steel for improved corrosion resistance, and thus reduced maintenance. Blue Moon Knife is hand ground and sharpened, and have very good overall fit and finish.
The oval-shaped handles are suitable for both right-handed and left-handed users. They are made of Magnolia wood with Brown Pakka Wood ferrule.
