Masuda Yoshihide Blue #1 Migaki Damascus Gyuto 240mm with Prisma Handle

Overview

The Masuda Yoshihide Blue #1 Migaki Damascus Gyuto 240mm with Prisma Handle pairs a Japanese carbon steel chef knife with a distinctive custom wa handle. Its long gyuto profile suits cooks who want room for slicing boneless proteins, cutting larger vegetables, and working through generous batches of prep. The 240mm size offers reach, but asks for more cutting-board space than a compact chef knife.

The blade combines a Blue #1 carbon steel core with soft iron Damascus cladding. A bright migaki finish reveals flowing layers beneath the textured upper blade. The pictured Prisma handle brings blue-green and pale golden figured wood tones together with a narrow red spacer, giving the polished steel a colorful counterpart.

This is a knife for someone who enjoys the character of carbon steel and is willing to wipe and dry it as they work. Both the exposed core and iron cladding can develop a patina and will rust if left wet.

Common Questions

Is a 240mm Masuda gyuto suitable for home cooks?

Yes, if you are comfortable using a longer knife and have enough board space. The extra blade length is useful for long slicing strokes and larger ingredients. Use controlled cuts through vegetables, fish, and boneless meat; avoid bones, frozen foods, and twisting the blade in a cut.

Does this knife come with the Prisma handle installed?

Yes. This listing is for a complete Masuda gyuto fitted with a custom Prisma wa handle. The photographs show the blue-green figured handle and red spacer. Natural grain and handmade finishing can vary between individual knives.

Is Blue #1 Damascus stainless?

No. Blue #1, also called Aogami #1, is carbon steel, and this knife's soft iron Damascus cladding is reactive too. Wipe the blade during use, wash it by hand, and dry it immediately. A developing patina is normal.

Care

Hand-wash with mild soap and dry the blade and handle thoroughly. Never soak the knife or put it in a dishwasher. Use a wood or soft synthetic cutting surface, such as a Hasegawa cutting board, and avoid glass, stone, and ceramic boards.

For longer storage, apply a thin coat of tsubaki knife oil to the clean, dry blade. Maintain the edge with suitable whetstones or professional sharpening.
