Masakage Koishi Gyuto 270mm

At 270mm, this is the longest gyuto in the Masakage Koishi line, built for cooks with ample prep space and plenty of ingredients to get through in a single session. Koishi knives are the highest end offering made by the Masakage cooperative, and this size shows off everything the line is known for.

The blade is stainless clad Aogami Super steel, one of the best alloys available for kitchen knives thanks to how well it takes and holds an edge. The stainless cladding helps reduce blade reactivity, and the tsuchime, or hammered, finish that gives the knife its name, since koishi means pebbles, adds a bit of anti stick performance on top of the rustic good looks. The handle is an octagonal cherry wood with a black pakka wood ferrule.

What Customers Are Saying:Reviewers consistently describe this gyuto as a favorite that holds an edge for weeks of daily work without needing a sharpening. One reviewer, a left handed chef, gave it four stars and noted the bevel was not a perfectly even 50/50 on their particular blade, with slightly more flat area above the grind on one side, a fair fit and finish note for anyone who relies on a precisely symmetrical edge.

Care Instructions:Aogami Super is reactive and one of the hardest carbon steels around, so wipe and dry the blade immediately after each use rather than letting it sit. Avoid leaving acidic foods against the blade for long stretches, and apply a light coat of camellia oil for longer term storage. Hand wash only, and a quality water stone with a final strop will keep the edge at its sharpest between full sharpenings.
