Hatsukokoro Yorokobi

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.
