Kyokokaji Shokei Shironiko Kurouchi Round Petty / Paring 60 mm (2.3") Fujimaki Handle

Intricate In-Hand Precision: The Curved Paring Specialist

Standard utility blades and flat paring knives are ill-suited for spherical ingredients and curved peeling. When fluting mushrooms, coring strawberries, peeling stone fruits, or sculpting classic French tourné root vegetables, straight edges drag and gouge.

The Kyokokaji Shokei Shironiko Kurouchi Round Petty 60 mm is engineered specifically for off-the-board, in-hand control. Measuring just 60 mm (2.3") with a curved cutting belly and an 18 mm blade profile, it acts as a direct extension of your thumb and forefinger. It glides around rounded contours and executes delicate tip work with microscopic accuracy.

Shirogami #2 (White Steel #2): Pure High-Carbon Slicing Bite

Forged from authentic Hitachi Shirogami #2 (White Steel #2) and hardened to 61–63 HRC, this blade offers the purest metallurgy in Japanese cutlery. Free from complex alloy carbides, White Steel #2 takes an extraordinarily acute, hair-whittling edge with unmatched ease of sharpening on Japanese whetstones.

Kurouchi Finish & Carbon Steel Maintenance

• Protective Kurouchi Scale: The upper portion of the blade retains its traditional Kurouchi (blacksmith forge) finish. This oxidized, non-reflective black scale serves as a natural barrier that helps resist rust on the blade flats.
• Patina as Protection: The exposed carbon steel along the edge will react naturally with acidic foods, developing a non-toxic, blue-gray patina. This patina is a prized hallmark of authentic carbon steel that shields the core steel from harmful red rust.
• Simple 2-Step Carbon Care:
1. Wipe the blade dry with a clean towel immediately after cutting acidic ingredients (such as citrus, shallots, or tomatoes).
2. Hand-wash with warm water and mild soap after use, dry completely, and store dry. Apply a drop of food-safe Camellia or mineral oil if storing for long periods. Never clean in a dishwasher.

Traditional Fujimaki (Rattan-Wrapped) Handle

Anchoring the half-tang blade is a traditional Fujimaki handle, crafted with tightly wound Japanese wisteria rattan. Used for centuries on specialized woodworking tools and traditional cutlery, rattan creates a textured, tactile grip that will not slip even when hands are wet with fruit juices. The compact 90 mm handle length and 18 mm thickness seat naturally in the palm for fatigue-free pinch grips.

Authorized Dealer Direct

Hasu-Seizo directly sources authentic artisan cutlery from traditional workshops across Japan. Before leaving our Seattle area warehouse, every blade is individually inspected to verify edge straightness, bevel uniformity, and tight rattan wrapping on the handle.

Sharpening & Care Guidelines

• Whetstone Maintenance: Shirogami #2 forms a burr effortlessly. Maintain the apex using a medium whetstone (#1000 grit) and refine on a fine finishing whetstone (#5000 to #8000 grit) followed by leather stropping.
• In-Hand Technique: This knife is designed for off-the-board peeling, coring, and carving. Avoid lateral prying or twisting against hard seeds.
• Prohibited Uses: Do not cut bones, frozen food, hard pits, or shells; hacking hard targets will cause the thin edge to chip.

Frequently Asked Questions

What is a 60 mm Round Petty knife best used for? A 60 mm Round Petty is designed for intricate, off-the-board prep, including peeling fruit, hulling strawberries, fluting mushrooms, coring produce, and shaping tourné vegetables where larger blades are awkward.
