Kurogane 黒金 Cleaver Knife – Strength in Forged Shadow
Named Kurogane (黒金), meaning "black steel" or "dark metal," this cleaver embodies the fusion of raw force and refined craftsmanship. With a surface that reflects the subdued gleam of forged iron and the quiet assurance of balance, this blade evokes the stillness before action — a tool shaped for precision, power, and poise.
The mirror-light finish and sandblasted texture echo traditional Japanese sword-polishing methods, paying homage to the legacy of blacksmith artisanship while ensuring a modern, labor-saving edge.
Crafted using a 3-layer composite forging method inspired by traditional Japanese san mai techniques, the blade features a hard X9Cr18MoV steel core — known for its excellent sharpness, edge retention, and corrosion resistance — flanked by tough SuS410 stainless steel cladding. This design offers the best of both worlds: a razor-sharp edge housed within protective, rust-resistant outer layers. With a Rockwell hardness of 58–60 HRC, this cleaver maintains its keen edge over time without becoming brittle, delivering both power and precision in every cut.
The warm-toned handle, hewn from premium padauk wood, provides both comfort and commanding grip, transforming every movement into an act of controlled strength. Whether slicing vegetables, portioning fish, or gliding through meat, this blade is a reliable companion for both professional chefs and dedicated home cooks.
