Where Seki is Japan's factory-scale capital, Sakai is its artisan heart — the home of hand-forged, single-bevel professional knives made under a distinctive division of labor: one specialist forges the blade (kaji), another sharpens it (togishi), another fits the handle, and a brand or shop ties it together. Many "makers" here are really coordinators of a chain of masters.

These nine profiles cover the Sakai houses most relevant to buyers worldwide — from the flagship Sakai Takayuki to legendary forges and the artisans who supply them. Every profile includes a company-profile block with verified contact details.
