Overview

The Masakage Mizu Blue #2 Kurouchi Petty 150 mm is your go-to utility knife for precision prep—think trimming silver skin, segmenting citrus, or artful garnishes. Forged by Takumi Ikeda in Echizen, Japan, it features a razor-retentive Aogami #2 core and a rustic kurouchi iron cladding that proudly patinas with use for natural corrosion resistance. At just 74 g, this petty feels feather-light yet sturdy, thanks to its 4 mm spine at the heel that tapers quickly for nimble tip work. The oval cherry-wood handle with blue-marble resin ferrule offers comfort in any grip and adds a splash of color to your kit.

Common Questions

Q: Is this petty knife good for home cooks? A: Absolutely. Its 150 mm length balances agility and reach, making it easier to handle than a full-size chef’s knife while still tackling on-board tasks like mincing garlic or chiffonading herbs.

Q: How do I care for Blue #2 steel with kurouchi finish? A: Rinse, wipe dry immediately, and store dry. A light coat of camellia or food-grade mineral oil after use helps prevent rust while the kurouchi finish and developing patina add extra protection.

Q: Does the handle need special maintenance? A: The stabilized resin ferrule is waterproof, and the cherry wood benefits from an occasional rub of tsubaki oil or Axe Wax to keep it looking fresh.
