There are Yanagiba, and then there are Ōzori Yanagiba — and the difference is immediately apparent the moment you pick one up. The Ōzori profile features a pronounced Sori (反り, recurve in the spine) that gives the blade a dramatically curved silhouette, and this shape is more than aesthetic. Much like a saber or shamshir outperforms a straight sword in a slashing motion, the curved edge of an Ōzori generates a far more effective slicing action when breaking down large cuts of protein like tuna — the arc keeps the blade in continuous contact through the draw, rather than the more vertical push-down motion a straight Yanagiba produces. It’s a profile you tend to see in high end Omakase kitchens where whole fish butchery happens at the pass, and beyond pure function it carries a visual presence at the cutting board that a standard Yanagiba simply can’t match. In certain settings this knife isn’t just a tool — it’s part of the performance.

The forging behind this line comes from the Yamatsuka family in Sakai — a name that serious knife enthusiasts will recognise immediately. A multi-generational blacksmithing lineage with family members still active across different generations today, the Yamatsuka name carries real weight in a city that takes its knifemaking traditions seriously. The sharpening is handled in-house by Yamawaki’s own team, and the result is a full mirror polish covering the entire blade — Hira, bevel and Urasuki — to a standard that is genuinely impressive. The Ginsan (Silver #3) steel core is fully stainless, which is a practical consideration for a knife that may be drawn out for presentation cutting at the pass. The mirror finish does show fingerprints and surface marks readily, so a light wipe-down habit goes a long way in keeping it presentation-ready.

Priced noticeably above comparable Ginsan single bevel lines like the Gintan series from Sakai Takayuki or Nakagawa’s offerings, this line earns its premium through a combination of the Ōzori profile’s rarity, the calibre of the mirror finish, the Yamatsuka forging pedigree, and a role that extends beyond pure utility into something closer to a ceremonial tool. For chefs who need a knife that performs and commands attention in equal measure, and for collectors drawn to something with genuine character and lineage, this is a compelling and hard to replicate option.
