Forged and sharpened by the same makers of the famous Komorebi line, the Yorokobi(よろこび) offers a unique copper damascus cladding with the much loved SLD steel. This combination is specially developed by Hitachi for Hatsukokoro, combining excellent artistic with the great performance. The overall grind and profile is heavily influenced by Sanjo area: very thick heel that aggressively tapers to a thin tip; a large blade (tip-to-heel length rather than tip-to-machi) and immaculate fit and finish.

Compared with its migaki finished twin sister, the Yorokobi(joy in Japanese) Kurouchi line doesn't fall short in its artistic appearance, in my opinion, Hatsukokoro's artistic approach on this line is more curated and thoughtful. Insteal letting the copper damascus spread across the blade, the pattern is resticted in the area right above the cladding line, moving up along the bevel is another layer of iron cladding, then the bevel finishes off into the Kurouchi surface. The layering of different material and their contrast make creates waves of pattern, emerging from the Kurouchi finish, flow down the bevel into the cutting edge, there is almost a sense of motion in it. This setup is rather complex but doesn't look busy, demonstrate a high level of artistic skill.

Complementing this beautiful finish is the SLD core steel, with similar composition to the SKD steel but less chromium, this tool steel can be heat treated to 63-64HRC and hold a thin edge for a extensive amount of time. However having only 8%chromium will make it a semi-stainless steel, but on this line the core steel have been put through a chemical etching, which gives it a dark colour and some resistance to rusting and discolouration.

This is a line made for those who fancy the passionate vibe that a copper damascus blade can give you, but don't want have that beauty shouting out loud. The dense orange pattern still emits a strong presence which is hard to miss, but it is well balanced and kept more subtle by the Kurouchi finish that takes up half of the blade. Remember that the copper and the core steel are both reactive to moisture and fingerprints, but if you keep them well looked after, knives from this Yorokobi like can keep bring you joy will its unique beauty.

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.

Construction: Sanami - Soft Iron Damascus 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.
Damascus Sanmai utilize damascus steel as the cladding material for the Sanmai construction, which adds aesthetic feature to the blade. However, the damascus cladding found on Japanese kitchen knives with carbon steel core are ususally made of soft iron, which means they too need to be maintained to stay pretty.
The soft cladding enables the thinning process to be a lot easier than a honyaki or monosteel construction. However, when the cladding is made of damascus, whether etched, polished or mirror polished, the thinning process will take a toll on the cladding, meaning the damascus won't look the same as when it was taken out of the box.

Finish: Kurouchi

Kurouchi refers to the rustic, unpolished finish found on the blade of many traditional Japanese kitchen knives. This blacksmith's finish is characterized by its dark, textured appearance, which is the result of leaving the blade forge-scale on the steel during production. Kurouchi finish not only adds a unique aesthetic appeal but also provides certain practical benefits. It acts as a protective layer against rust and corrosion, and helps to reduce food sticking to the blade during cutting. Commonly seen on high-quality, hand-forged knives, the kurouchi finish emphasizes the artisanal nature of the knife and its heritage, making each piece distinctively unique.
