Yu Kurosaki - Kokusen AS Petty 130mm

Yu Kurosaki is one of the most recognisable young bladesmiths in Japan — and for good reason. Working out of Takefu Knife Village, Kurosaki blends elite performance with some of the most striking finishes in the industry, from his signature Shizuku “water drop” pattern to the bold Fujin “wind god” texture.

Behind the eye-catching looks is a maker obsessed with cutting performance. His knives are known for laser-thin grinds, razor-sharp edges, and incredibly consistent heat treatment across steels like SG2/R2, Aogami Super, and VG-10.

If you want a knife that works as hard as it wows — a blade that’s fast, light, and unforgettable — Yu Kurosaki is the perfect match. Pure energy, top-tier craftsmanship, and unmistakable style.
