Overview

Aritsugu is a Japanese knifemaker specializing in handcrafted kitchen knives and cooking utensils with a heritage spanning over 450 years. The company is recognized as one of the oldest cutlery shops in the world and maintains a strong reputation among professional chefs, sushi vendors, and culinary enthusiasts globally. Aritsugu knives are known for their exceptional sharpness, precision blade work, and use of high-quality Japanese steel, particularly Shirogami II White Steel and Aogami II Blue Steel. The brand holds particular prestige in Japanese cuisine circles, where its long-bladed knives are prized for fish and eel filleting in sushi preparation.

History

Aritsugu was founded in 1560 in Kyoto by Fujiwara Aritsugu, who initially served as a master swordsmith for the Imperial House of Japan. The company transitioned from samurai sword manufacturing to kitchen knives and cooking utensils after the end of feudal warfare, leveraging its blade-forging expertise. In 1919, the Kyoto proprietors established a Tokyo branch to employ their sons, initially setting up in Nihonbashi fish market before relocating to Tsukiji after the 1923 Great Kanto Earthquake. The company has remained family-operated for generations and continues to operate both its original Kyoto location in Nishiki Market and its Tokyo Tsukiji location.

Reputation

Aritsugu is regarded as a gold standard in professional culinary circles, with knives used in Michelin-starred kitchens and sushi bars throughout Japan and internationally. The brand is highly respected among professional chefs and serious enthusiasts for its exceptional craftsmanship, sharpness, and heritage. A notable strength is the company's commitment to after-sales service, including sharpening and repairs to ensure long-term knife performance. The primary consideration for potential buyers is that high-carbon steel variants require diligent maintenance to prevent rust, making them less suitable for casual or low-maintenance users compared to stainless steel alternatives.
