Forged throughout an amazing 800 years of history, the Kanetsune knives are impressively strong, beautiful and exceedingly sharp. The Kitasho Company limited is the name behind this trusted brand, and they have been established since 1948 in Seki City, Japan (affectionately known as the city of blades). The company are actively and passionately enthused by their work, and continue to make a wide range of the finest swords, knives, cutlery, axes etc. The company uses three main types of steel in the production of their knives and swords. First of all there is White steel (known as Shirogami in Japan). This is a refined Carbon steel which does not contain any ingredients such as Blue steel. Secondly they use Blue steel (known as Aogami in Japan). With this steel they add Tungsten and Chromium to White steel. This makes the steel far more durable. Thirdly they use Super Blue Steel (known as Aogami Super in Japan). This is their highest grade of steel and has high levels of Carbon and Chrome to make it extremely strong, hard, resistant to corrosion and is able to keep a strong edge for long periods of time. They use the steel from Hitachi Metals Ltd, as their steels are high grade, and are often found in electronic devices. They also make Yasuki Hagane (YSS Yasuki speciality steel) for the cutlery industry. White steel has Rockwell hardness rating of 60-61, Blue steel has the 61-62 and super Blue steel has a 62-63 HRC rating.
