Tadafusa "Seido" Blue 2 Nashiji Gyuto 240mmKnife Information Tadafusa manufacture their knives in the city of Sanjo, well known across Japan as the town of blacksmiths. The likes of Yoshikane, Hinoura, and Kawamura all hail from the same city. Tadafusa was founded in 1948 by Sone Torasaburo, who began making sickles, knives, and other bladed tools using traditional forging methods, but then began to specialise in kitchen knives, which has culminated in the immaculate pieces you see here.
