Wa Handle (和柄 — Traditional Japanese Handle)
Lightweight wooden handle with hidden partial tang
Traditional Japanese wood handle mounted with a heated hidden tang. Extremely light (30–45g), shifting the knife's center of balance forward toward the blade, which makes the knife feel fast, agile, and natural in a pinch grip.

Wa Handle Profiles: Octagonal, D-Shape, Oval
Hakkaku (8-sided), Shinogi (D-shape), and Maru (oval)
• Octagonal (Hakkaku - 八角): Symmetrical, with crisp angled faces; it suits right- and left-handed grips alike. • D-Shape (Shinogi - 鎬): Asymmetrical ridge fitting the curl of right-handed fingers. • Oval (Maru - 丸): Smooth, rounded, traditional simplicity.

Handle Woods & Ferrules (Katsura)
Magnolia (Ho), Walnut, Ebony, Cherry, Buffalo Horn
• Ho Wood (Japanese Magnolia): The classic sushi-chef choice—light, soft, and slightly expands when wet to provide a non-slip grip. • Walnut & Cherry: Warm, durable, mid-weight hardwoods. • Ebony & Rosewood: Dense, luxurious dark woods with grounding weight. • Ferrule (Katsura): The collar at the top of the handle, traditionally crafted from water buffalo horn, Pakkawood, or nickel-silver.

Yo Handle (洋柄 — Western Handle)
Full-tang contoured handle secured with rivets
Western-style handle constructed with a full or partial metal tang sandwiched between composite (Pakkawood, Micarta) or wood scales secured with 2–3 metal rivets.
