Hatsukokoro Mercury Petty Kurozome Damascus 150mm (5.9") [Mono Olivewood]
Built around a high-performance SG2 core, this Hatsukokoro Petty takes and holds an exceptional edge, slicing effortlessly through every ingredient. A true all-rounder for prep, filleting, and fine-detail work, it combines striking aesthetics with lasting durability—a kitchen knife with character that can be passed down to the next generation.
BLADE SHAPE:
The Petty is excellent for peeling and preparing vegetables, and thanks to its thin, nimble blade. Ideal for precise and controlled cutting tasks: filleting portioned fish, cutting poultry, slicing small pieces of cured meats, making it a highly functional tool for professional and home kitchens alike.
The blade is thin with a slightly stiff spine, tapering to a fine, agile tip for precise, controlled cuts. Its lower height limits pinch-grip clearance, but the thin grind behind the edge allows it to glide easily through small to medium ingredients. A smooth edge profile from heel to tip supports gentle rocking and clean slicing, while the rear-set balance point offers excellent control across different grips.
STEEL:
SG2 steel is a powder steel, renowned for its hardness and subsequent edge retention—due to a high carbon (C) content of 1.5%. The steel is also high in chromium (Cr)—around 15%, which adds to corrosion resistance and Molybdenum (Mo) that improves the blade’s wear resistance. SG2 steel blades will be able to achieve a fine sharpness due to the fine microstructure of the steel and will keep it—without having to worry about maintenance and corrosion.
LAMINATION:
The hard SG2 core is sandwiched between 15 layers of softer stainless steel on each side of the blade. This san-mai construction protects the delicate core from impacts and everyday use while keeping the blade strong, durable, and resistant to breakage.
GEOMETRY:
A convex (hamaguri) grind features an outward-curving, clam-shaped edge inspired by traditional katana blades. It improves sharpness, food release, and edge strength by keeping more steel behind the edge.
BLADE FINISH:
The blade features a black-etched kurozome Damascus finish, which is slightly raised—allowing you to glide through different ingredients without drag or resistance. The spine and corners are carefully polished, with a flawlessly finished choil and polished edges for a refined, ergonomic feel. The rounded choil and spine prevent hand fatigue, even during extended use.
HANDLE:
The knife features a Japanese (Wa) octagon handle crafted from a single piece of olive wood—an unusual choice for Japanese knives. The handle is expertly finished with a tight seal and flawless fit. The warm tone of the olive wood beautifully complements the dark, etched Damascus blade.
