$319.95
DESCRIPTION
Reach for this when you've got a board full of vegetables and want a blade that moves fast without fighting you. The 7.5-inch Santoku is longer than the standard 7-inch version, which gives you more belly for a single push cut through a whole head of wombok or a thick daikon round without breaking it into two strokes. It's the knife you'll default to on most weeknight prep - nimble enough for fine herb work, long enough for serious volume.
The Santoku Advantage
A Santoku has a flatter belly than a Western chef knife, which makes it naturally suited to a push-cut motion rather than rocking. That means cleaner cuts on soft vegetables like tomatoes or ripe mushrooms, where a rocking motion bruises the cut face. The 7.5-inch length sits between a standard Santoku and a full chef knife, so you get the push-cut efficiency with enough reach to handle larger tasks without switching blades. It's the kind of knife that earns a permanent spot on the left side of the board.
73-Layer Damascus on a Powder Steel Core
The core is 14Cr14MoVNb powder steel, heat-treated to 62 HRC. That hardness level is what lets the edge stay sharp through a long prep session on hard vegetables like butternut squash and raw beetroot, where softer steels start to lose their bite. Wrapped in 73 layers of Damascus cladding for chip resistance on the shoulders, rosewood handle, hidden tang construction, and a balance point that sits naturally in a pinch grip for fatigue-free extended prep.

The X03 Series — Xinzuo × Mauro Uliassi
Designed for a three-Michelin-star kitchen
A collaboration with Mauro Uliassi — the Italian chef whose restaurant held three Michelin stars from 2019 to 2025 — co-designed with Steve Cheng. The wavy Damascus is forged, not laser-etched. Made by hand in Yangjiang, China — the city of knives, with roughly 1,400 years of blade-making heritage.
In stock. Ships from Australia. Hand-wash only.
The all-rounder
One knife for almost everything.
The santoku — 'three virtues': meat, fish and vegetables. A flatter profile than a Western chef's knife and a rounded tip mean less rocking and more clean, downward slices. At 7.5 inches it's nimble for everyday prep yet long enough to work through a cabbage or a chicken breast.
- 190 mm blade
- 15° per side
- 62±2 HRC
73-layer Damascus
73 layers. One edge that lasts.
A 14Cr14MoVNb powder-steel core — the Chinese equivalent of SG2/R2 — hardened to 62±2 HRC with vacuum heat treatment and a deep-freeze cryo cycle, then folded into 73 layers of Damascus. A true double bevel, forged, not laser-etched.

Care & questions
How do I clean and care for it?
Hand-wash with warm soapy water and dry it straight away. Not dishwasher safe. Store it in the included wooden saya or on a magnetic strip to protect the edge.
Will the edge chip?
The 14Cr14MoVNb powder-steel core at 62±2 HRC holds a fine edge. Like any hard Japanese-style blade, keep it to food — avoid bone, frozen food and twisting.
Is it made in Japan?
No. It's hand-made in Yangjiang, China — the traditional Chinese city of knives — using a 14Cr14MoVNb powder steel equivalent to SG2/R2, as part of the Xinzuo × Mauro Uliassi collaboration.
What is a santoku for?
Everyday all-round prep — vegetables, boneless meat and fish. Its flat edge favours clean push-cuts over rocking, and the compact 190 mm blade keeps it nimble.
Does it include a sheath?
Yes — a matching wooden saya is included in the gift box.
Can I have it engraved?
Yes — choose the engraving option in the buy box above before adding to cart.
