The Raijin (雷神, God of Thunder) is one of Yu Kurosaki's most recognised lines, and after more than a decade the name returns with a meaningful facelift rather than just a cosmetic refresh. For those who owned or coveted the original, the differences are immediately visible — and for those coming to it fresh, this is the version worth knowing.

The most striking change is the Tsuchime pattern. The original Raijin featured long indentations running in two directions at roughly 60 degrees to each other, creating a brick-like texture that was bold but relatively uniform. The new version tightens that angle to around 30 degrees, forming distinct diamond shapes across the Hira. The facets are larger and more dramatic than before — almost sculptural, with strong angular planes that catch light in a way the original couldn't match. Running along the cladding line is a thin copper shim between the cladding and core steel, adding a warm orange line that traces the organic boundary of the blade. It's a more considered and layered aesthetic than the original, and one of the more visually striking knives in Kurosaki's current catalogue.

The steel has been updated to VG10W — Takefu Special Steel's tungsten-enhanced VG10 — which forms finer tungsten carbides that improve edge retention without changing the hardness or the familiar maintenance-free character that made VG10 such an enduring choice. The geometry has been updated too, moving from the concave grind of the original to a convex design similar to what Kurosaki uses on the Sasame line. This shift meaningfully improves food release — the blade curves away from the slice as it passes through rather than relying solely on the Shinogi line transition — while the thin Echizen spine keeps wedging in dense produce well controlled. It's a more complete geometry than what the original offered.

The profile is worth noting for those navigating Kurosaki's current lineup. Unlike the Senko with its dramatically dropped neck and K-tip, or the Gekko with its similarly expressive profile, the Raijin takes a more traditional shape — a gentle, balanced drop near the handle that feels immediately comfortable across a range of cutting styles. Beyond the profile, the Raijin is a forged knife and that shows in how it feels in hand — noticeably stiffer and more substantial than the stamped Senko and Gekko, with a confidence and rigidity that makes it the more premium handling experience of the three. For anyone who found those profiles too unconventional, or simply wants that extra solidity in hand, the Raijin is the natural entry point into Kurosaki's catalogue.

At 499 AUD for a 210mm Gyuto, the Raijin sits at the standard price point for a forged Takefu stainless steel knife of this calibre. For a line that carries a legacy name, delivers genuine performance improvements over its predecessor, and looks better than it ever has, that price is entirely justified.
