Makoto Kurosaki SG2 Bunka 240mm with Custom Prisma Handles

The Makoto Kurosaki SG2 Bunka 240mm is an unusual interpretation of the Bunka profile. At 240mm, it has the reach of a full-size Gyuto and the precision of a long K-tip. Makoto Kurosaki identifies the design as a Bunka, while some users may describe its proportions as a Kiritsuke-style Gyuto.

This Tokushu configuration pairs Makoto Kurosaki's SG2 blade with custom handles by Prisma Knife. Current variants include Amethyst Skull, Nebula Burl and Turquoise Aura; availability varies by handle.

Why Makoto Calls It a 240mm Bunka

Most Bunka knives are shorter, but this model extends the profile to 240mm for additional slicing length while retaining a flatter edge section and angular K-tip. It is suited to vegetables, herbs, boneless proteins, fish and long slicing cuts, while the fine tip supports detailed work.

SG2 Powder Steel

The core is made from SG2, also known as R2 powder steel. SG2 is valued for edge retention, high hardness, fine carbide structure and corrosion resistance. It can take a refined edge while requiring less maintenance than reactive carbon steels.

This is not a Damascus blade. The visible pattern comes from a hammered decorative finish across the upper blade. Below it, a soft Kasumi transition leads into a highlighted cladding line and polished cutting bevel.

Hammered Pattern, Kasumi Finish and Highlighted Cladding Line

The upper blade has a patterned hammered texture. The lower section transitions through a soft Kasumi finish before meeting the bright cladding line and exposed SG2 cutting core.

Care and Maintenance

Hand wash and dry immediately after use. Do not place the knife in a dishwasher or use it on bones, frozen food, glass, stone or ceramic boards. A Hasegawa Pro Cutting Board can help protect the fine SG2 edge. Light maintenance on the Tokushu Knife Premium XL Buffalo Leather Strop can extend the time between sharpenings, and our professional knife sharpening service is available for customers who want the edge refined before use.
