X03 Uliassi Series
The Xinzuo X03 Uliassi Series is built in direct collaboration with Mauro Uliassi, a three-Michelin-star chef whose restaurant on the Adriatic coast has held its stars since 2012.
The knives in this collection were developed to meet the specific demands of a professional kitchen where edge retention and consistent geometry matter across hundreds of covers a service. For home cooks who want the closest thing to a working chef's tool within the Xinzuo range, this is the series to choose.

Inside the X03 Uliassi Series
Premium 14Cr14MoVNb Powder Steel Core
The blade core is 14Cr14MoVNb powder steel, produced through powder metallurgy rather than conventional forging. Conventional forged steel has an uneven grain structure because carbon and alloying elements distribute unevenly as the melt cools. Powder metallurgy starts with pre-alloyed powder sintered under controlled pressure, producing a far more uniform grain. That finer structure lets the X03 reach 62±2 HRC without the brittleness risk that hardness level carries in a forged blade, and it holds the edge longer through demanding prep. This same alloy underpins the Lan Series (B37), which pairs it with olive wood handles for a different series identity.
73-Layer Damascus Cladding
The powder steel core is wrapped in 73 layers of Damascus cladding, six more than the 67-layer construction used across the rest of the Xinzuo damascus range. The additional layers produce a visibly denser wave pattern on the flats of the blade, and the tighter fold structure adds chip resistance along the shoulders where the cladding meets the core. Each knife is hand-polished to bring out the contrast between the softer outer layers and the harder core, with the pattern running the full length of the blade from heel to tip.
Rosewood Handle, Hidden Tang
The handle is shaped from Rosewood, a dense hardwood with a rich reddish-brown grain and a natural resistance to moisture absorption that makes it stable across repeated wash-and-dry cycles. The hidden tang construction draws the handle material flush against the blade, giving the knife a clean, integrated profile without exposed rivets or bolsters. The grip sits naturally in a pinch hold at the heel, which is how a chef knife is meant to be used for extended prep, and the weight distribution is biased forward to reduce hand fatigue on long sessions.
