Who is Masamoto Sohonten and what are they known for?

What the research shows

Masamoto Sohonten is a Tokyo knife maker founded in 1866 and run by the same family for generations. In the market, it is best known for traditional Japanese professional knives, especially single-bevel sushi and sashimi knives, and for the KS series gyuto. The broader consensus is that Masamoto has long been a reference name for chefs, with a reputation built on consistency, sharp cutting performance, and a deep professional following rather than flashy styling.

The Knives & Stones take

Masamoto Sohonten is a Tokyo maker founded in 1866, and the honest market read is simple: they’re one of the names people bring up when they talk about serious Japanese professional knives, especially traditional single-bevel knives and the KS series Gyuto. If you want the classic reference point, that’s Masamoto. If you want more variety around the same general lane, I’d look at Sakai Takayuki for classic Sakai knives, or Satoshi Nakagawa for single bevels and heat treatment across hitachi steels.

My take: Masamoto makes sense when the buyer cares about proven, traditional geometry over trendiness. The signature steel here is White #2 / Swedish Steel, which fits that old-school professional brief. I’d steer someone to Masamoto when they want a benchmark name with a long track record, not a flashy experiment.

Read more The Masamoto KS series, particularly the KS double bevel line up, including the unicron KS 3124, is loved by many many professional chefs and enthusiasts because of its unique and excellent profile; also because it is super light and nimble. Arguably the only problem? The rustic carbon steel used in the KS line can be problematic during the busy service sessions in a western kitchen. As a result, Masamoto created the SW series, which is the stainless equivalent of the white steel (KS) line, employing the same great cutting performance without the need to worry about the rust. The Swedish steel is very refined, offer decent hardness and excellent toughness.
