Xinzuo X05Z Zhen Series Nakiri Knife 180 mm (7”) – ZDP-189, 3-Layer

The XINZUO Zhen Series Nakiri Knife 180mm (7”) is a purpose-built vegetable knife designed for fast, clean prep. Its tall blade and straight cutting edge make it ideal for push-chopping, slicing, and shredding vegetables and fruits with consistent board contact and easy control.

A nakiri is made for produce work—not for impact tasks. Use it for onions, cabbage, carrots, herbs, and everyday veg prep, and avoid bones, frozen foods, hard shells, and twisting/prying in cuts to protect the fine edge.

The blade features a Hitachi ZDP-189 powder steel core hardened to 65–67 HRC. In practical terms, ZDP-189 is known for very high wear resistance, which helps the edge stay sharp longer through lots of slicing and chopping. Because it’s a very hard, edge-retentive steel, it rewards smooth technique and careful use around hard ingredients.

Construction is 3-layer: a ZDP-189 core with SUS405 stainless steel outer layers to support the edge and improve day-to-day ease of care. The edge is finished to 15±1° per side for a keen, precise feel, and blade thickness is listed at about 2.1mm for a balanced blend of control and stability.

Comfort details matter on a nakiri used for repetitive prep: the blade spine and back are made with rounded corners to reduce pressure and accidental finger contact during longer sessions. A hand-brushed blade surface highlights a clean, delicate metal texture.

The classic octagonal handle combines Desert Ironwood with White Bull Horn accents for a secure, traditional grip. Listed dimensions are 337mm overall length, 183mm blade length, and 138mm handle length, with a net weight of 185g.

Care of the knife:

Hand wash only. Rinse and wipe clean promptly after use, then dry thoroughly before storing. Do not soak and never put the knife in the dishwasher.

Use a wood or soft plastic cutting board to protect the edge. Avoid twisting, prying, and contact with bones, pits, shells, and frozen foods—very hard edges can micro-chip if used on hard impacts.

Store safely in a block, on a magnetic rack, or with an edge guard. Sharpen as needed with quality stones and light, controlled pressure to preserve the keen edge geometry.
