The three blade towns behind the knives you own

Tsubame-Sanjo, Seki, and Sakai each specialize differently. Knowing which town made your knife explains its design choices.

Tsubame-Sanjo (Niigata)

Tojiro forges in Tsubame-Sanjo; its DP series clads a VG10 core in softer stainless so home users can sharpen it easily. Global's maker Yoshida Metal Industry is in Tsubame — it shipped the world's first all-stainless one-piece knife (blade to handle) in 1983.

Seki (Gifu)

Seki has forged blades since the age of its medieval swordsmiths. Kai makes its export flagship Shun here — 33-layer Damascus over a VG-MAX core, with roughly 97% of production shipped overseas — alongside the home-market Seki Magoroku line. MAC's blades are also produced in Seki, while the company headquarters sits in Sakai.

Sakai (Osaka)

Sakai remains the professional kitchen-knife town, and its shops publish the deepest free sharpening columns in Japanese — Ichimonji Mitsuhide and Jikko among them. MAC (est. 1965, over 25 million knives sold) is headquartered here.
