Masutani, also known as Kunihira, always striving to keep the traditional balance point, profile, and a lightweight knives. Most western webshops will name the ”Masutani”, suggesting that the blacksmith is Masutani and that he makes the knives. The company is called Kunihira Sairyu, which is also what the kanji says ”Kunihira”. Therefore the Japanese-based webshops will name it Kunihira Sairyu and won’t mention Masutani.
