The SUI series is a unique and one-off project from Ryusen, so stock is very limited!

The meaning of the "翠 (SUI)"

Ryusen created the "梵天雲龍: 翠(SUI) series" with inspiration from beautiful deep green of jade(翡翠). Jade symbolizes "prosperity", "longevity" and "happiness", and has a mysterious charm that attracts everyone.

The coloring of handle was finished with the "traditional Echizen Negoro-nuri lacquerware technique" to express beautiful jade green color which appears through a faded color of the black‐lacquered surface by polishing, that was pursued a deep beauty composed of the different tones of green and black.

This is a masterpiece that you can be satisfied with not only cutting quality, but also traditional Japanese beauty.

Features of the (Bonten Unryu) SUI series

The blade of the SUI series, is constructed identical as the Bonten Unryu series. It has a core of VG-10, with on each side 31 layers of stainless Damascus steel. The blade is relatively thin, with a medium / light weight, but not as thin as a laser.

The VG-10 steel is dipped in a salt bath after forging, which results in the correct hardness and toughness of the steel. The result is that it can be sharpened very thin, but it also remains sharp for a very long time. Ryusen is a master in the geometry of the blade: thin and razor-sharp.

Elwin de Veld about Ryusen knives

When I started sharpening knives, I sometimes got hold of a very special model, probably imported by a customer themselves. A Ryusen knife was one of them. To precisely measure the quality of steel, there is no better measure than the actual manual sharpening of a knife: Ryusen belongs to the absolute top in the world of handmade Japanese kitchen knives.

Until some time ago, Ryusen made various models on OEM base in Echizen, but recently they focus entirely on their own company. Ryusen has spent a lot of time researching in the field of manufacturing (forging, hardening, grinding and finishing), as well as receiving feedback from the professional end user. Their dedication, perseverance and only settling for the very best ensure that every knife is perfectly finished and meets the highest requirements of a completely handmade chef's knife. The complete process from forging to the design of the box is carried out by Ryusen in-house. I am very proud to be an importer and a reliable distributor for Ryusen.
