If you are familiar with the older Yu Kurosaki knives, you would remember the Shizuku, Fujin and Raijin that all comes in two different core steels: R2 and Aogami Super. The Senko series inherent that tradition and offer the Kokusen(黒閃, Black Flash) as the Aogami Super alternative to the Senko line. As the name implies, the blade comes in a darker Kurouchi finish, which makes it easy to distinct from the R2 Senko.

The Kokusen Ei can be considered identical to the Senko Ei, except the core steel. They boast Yu Kurosaki's signature concave grind that bring the thickness down significantly behind the edge. Pairing with the thin spine thickness, this laser feels weightless whether you are handling it of cutting through dense roots. The Ei(鋭, acute) name is given to the K-tip designs, the very steep angle at the end of the knife forms a very thin tip which helps a lot when dosing precise slices.

The cladding of this line is stainless, which is a big plus in easy of maintenance, whether you are an enthusiastic knife collector or a chef in professional kitchen, you could benefit from the sharpness of the carbon steel core without having patina all over the blade. The cladding features the star shaped hammer pattern, which is a distinct character that identify the Senko line.

If you you are looking for a high performance knife from a famous maker with a characterful finish, Senko families will definitely fit in that place, the addition of the Kokusen can satisfy the carbon steel lovers with the top notch Aogami Super steel, ensuring a even finer Kireaji that people always love from Yu Kurosaki.

Care Instruction

Don't cut hard things! Japanese knives are brittle so bone hacking is a NO NO!
Wash with neutral detergent after use, and wipe dry;
Please don't wash knife with dishwasher, it will damage the wood handle;
Be careful not to leave the knife close to a heat source for a long time;
It is a lot more dangerous to cut with a blunt knife than a sharp knife!
It is best to sharpen a Japanese knife regularly on a waterstone.
Oil the (carbon) knife if storing for an extended period of time to prevent rust.

Yu Kurosaki

Yu Kurosaki, a master artisan in his forties, is renowned in Japanese knife making for his hand-forged blades, earning him awards and global recognition. His journey began in his teenage years, and after a twelve-year apprenticeship under Hiroshi Kato, he established his own workshop in 2014. Kurosaki excels not only in craftsmanship but also in innovative finishing techniques, notably seen in his Tsuchime and Suminagashi finishes. Recognized by the Japanese government as a “master blacksmith,” he is the youngest to receive this title. Highly esteemed for his unconventional blade designs, Kurosaki consistently surprises observers with each new creation. By blending modern metallurgical technologies with traditional forging methods, his knives boast unmatched quality, sharpness, and performance, cementing his status as a leading figure in the industry.

Profile: Gyuto

Chefs Knife
A Japanese chef's knife is known as a gyuto (牛刀ぎゅうとう） gyūtō?), literally meaning 'beef knife'. Its blade resembles a flatter version of a French chef's knife. Japanese cutlery is known for sharpness due to its acute blade geometry, and the hardness of the steel used, sometimes exceeding 60 HRC on the Rockwell Scale A typical western chef's knife may be sharpened to an edge angle of 20-22°, while a Japanese gyuto generally has a sharper edge angle of 15-18° (or even lower), which requires a harder, more brittle grade of steel. In recent years Japanese gyuto have gained in popularity with western chefs.

A modern chef's knife is a multi-purpose knife designed to perform well at many differing kitchen tasks, rather than excelling at any one in particular. It can be used for mincing, slicing, and chopping vegetables, slicing meat, and disjointing large cuts.

Steel: Blue Super / Aogami Super
Aogami Super steel, also known as Blue Super Steel, is highly esteemed among Japanese carbon steels for its exceptional qualities. Produced by Hitachi Metals Ltd., this steel surpasses Blue Steel No.1 in its composition, featuring higher amounts of carbon, chromium, and tungsten, with the addition of molybdenum. Aogami Super is celebrated for its remarkable edge sharpness and superior edge retention capabilities. It can achieve high levels of hardness without becoming brittle, a characteristic that sets it apart and endears it to knife enthusiasts worldwide. The steel's enhanced carbon content enables it to maintain sharpness for extended periods, while the added chromium aids in rust resistance. A touch of vanadium increases its toughness, making it less prone to chipping. These attributes make Aogami Super one of the most revered high carbon steels globally, often described as a knife nerd's dream for its balance of hardness, durability, and maintenance ease.

Construction: Sanmai - Stainless Clad

Sanmai(Three-Piece) is a common construction for double bevel knives where two pieces of softer cladding steel are forgewelded to each side of a harder core steel. The harder but more brittle core steel will form the hard cutting edge after heat treating, and the softer cladding will support the core to increase the overall strength of the blade.
The soft cladding enables the thinning process to be a lot easier than a honyaki or monosteel construction. And in the case where the cladding steel are stainless in nature, it can offer protection for the carbon or semi-stainless cores against rusting and discoluoring.

Finish: Kurouchi Tsuchime

The Kurouch Tsuchime is a combination of the raw, organic black finish and the characterful hammered Tsuchime finish. It is commonly seen as the Kurouchi finish will keep the original black scale of the billet unpolished after forging, the texture from the forging process will be also kept, allowing all kinds of patterns and indentations to be introduced to the blade. As a combination of Kurouchi and Tsuchime, this finish also inherents their benifits: reduce drag, help with food release and protect the steel from rusting. Over all Kurouchi Tsuchime is a practical and esthetically unique finish.
