DESCRIPTION

Nimble, responsive, and incredibly sharp. The Zhen Series 5" Utility Knife (Petty) is the perfect companion for tasks where a large chef's knife feels clumsy. Whether you are peeling fruit in-hand, trimming silverskin from tenderloins, or mincing shallots, this blade acts as an extension of your finger.

Extreme Hardness & Edge Retention

Small knives often suffer from dulling quickly due to frequent contact with the board. Not this one. Forged with a core of Japanese Blue Steel No. 2 (Aogami #2) and vacuum heat-treated to 62–64 HRC, this utility knife holds a razor edge significantly longer than standard stainless alternatives. The "San Mai" cladding protects the body of the knife, leaving the reactive carbon edge exposed for precision work.

Premium Natural Materials

The handle combines natural Maple Wood with a White Buffalo Horn ferrule. This lightweight construction allows for exceptional agility and fine control, essential for a knife of this size.

⚠ IMPORTANT: High Carbon Steel Care

Special care is required for this blade. The Blue Steel core is highly reactive.

  • Water is the Enemy: Wipe dry immediately. Do not leave on a wet cutting board.
  • Acidic Foods: When cutting citrus or tomatoes, wipe the blade frequently during use to prevent corrosion.
  • Patina: A dark patina will form on the edge. This is normal and desirable.
  • Ideally Suited For: Chefs and enthusiasts who understand carbon steel maintenance.
  • Blade Steel: 3-Layer Japanese Blue Steel No. 2 (Aogami #2)
  • Hardness: 62–64 HRC (Vacuum Heat Treated & Deep Freeze)
  • Handle: Maple Wood + White Buffalo Horn
  • Blade Profile: 5-inch Utility (Petty)
  • Use: Peeling, trimming, small vegetable prep, garnish work.
  • Series: Zhen (PM8M)
  • Model: PM8M-WY

3-Layer Composite
The reactive Blue Steel core is sandwiched between stainless cladding layers. This protects the sides of the blade while leaving the cutting edge exposed for maximum sharpness.

Aogami #2 (Blue Steel No. 2) is a legendary Japanese carbon steel, revered by bladesmiths for its ability to take the keenest edge of any kitchen steel. The 3-layer composite construction wraps the reactive carbon core in stainless cladding for protection — but make no mistake, this is a knife that demands respect. It will rust if left wet. That's the trade-off for the finest edge available.
62-64 HRC

Superior Hardness

Second only to the X05Z in our range. This hardness allows an incredibly fine, keen edge that holds through extended prep sessions.
Blue Steel No. 2

Japanese Carbon Legend

Aogami #2 has been the steel of choice for Japanese blacksmiths for generations. It takes an edge that stainless steels simply cannot match.
Reactive Steel

Requires Active Care

This is non-stainless steel. It will develop a patina (normal and desirable) and will rust if left wet. Dry immediately after every use.

THE SHARPEST EDGE. THE HIGHEST STANDARD.

Carbon Steel for the Dedicated Cook

 Blue Steel No. 2 takes an edge that stainless steels simply cannot match. The grain structure is so fine, so tight, that the cutting edge can be honed to a level of sharpness that changes how food feels under your blade. This is the knife for cooks who understand that the best tools demand the most care.

THE CARBON TRADE-OFF

Here's the honest truth: Blue Steel No. 2 will rust if you leave it wet. It will develop a patina — a dark, mottled surface that's completely normal and actually protects the steel over time. In exchange, you get the sharpest, most refined edge available in any Xinzuo knife. For many cooks, that trade-off is exactly what they're looking for.

Handle Design

Maple Wood &
White Buffalo Horn

The PM8M handle honours Japanese tradition with light maple wood and white buffalo horn in an octagonal shape. Maple is a tight-grained hardwood that's lightweight yet strong — the perfect counterbalance to the dense carbon steel blade. The octagonal cross-section gives you intuitive control over the blade's angle, essential for the precision cutting that Blue Steel enables.

Traditional

Japanese octagonal shape for precise grip and blade control.

Lightweight

Maple wood balances the dense carbon steel blade perfectly.

Refined

White buffalo horn bolster adds elegance and structural strength.

Why Choose
Carbon Steel

The PM8M Zhen Series exists for one reason: to offer the finest cutting edge possible. If you're a cook who hand-washes and dries your knives immediately, who appreciates the ritual of maintaining a blade, and who values sharpness above all else — this is your knife. There's nothing else like it in the Xinzuo range.

With just 3 knife types — Utility, Santoku, and Bunka — the PM8M is deliberately focused. These are the essential cutting knives, the ones that benefit most from Blue Steel's extraordinary edge. Each blade is individually heat-treated to 62-64 HRC and arrives in a premium gift box.

Complete Your Collection

The perfect sidearm to the PM8M 7" Santoku or 8.5" Bunka.

The Bunka is the ultimate fusion of agility and aggression. With its distinctive "K-Tip" (reverse tanto) profile, the Zhen Series 8.5" Bunka is designed for chefs who demand laser-like precision. It functions like a chef's knife for slicing but offers the intricate tip control of a much smaller blade.

Legendary Japanese Aogami #2 Steel

This is not an ordinary stainless knife; this is pure cutting performance. The core is forged from Japanese Blue Steel No. 2 (Aogami #2), a high-carbon steel revered by sushi masters for its ability to take a frighteningly sharp edge. Heat-treated to an ultra-hard 62–64 HRC using vacuum heating and deep freeze technology, this blade offers edge retention that standard kitchen knives simply cannot match. It is clad in softer stainless layers (San Mai construction) to protect the core, leaving only the cutting edge exposed.

Traditional Elegance

The handle is a work of art, crafted from blonde Maple Wood paired with a genuine White Buffalo Horn bolster. This traditional Japanese Wa-style handle is lightweight, balancing the knife perfectly forward to let the sharp edge do the work for you.

⚠ IMPORTANT: High Carbon Steel Care

This is a high-performance tool, not a low-maintenance one. The cutting core is non-stainless high-carbon steel.

  • Rust Risk: It WILL rust if left wet, even for a few minutes. You must wipe it dry immediately after use.
  • Patina: Over time, the edge will develop a blue/grey patina. This is natural and protects the steel.
  • Acid Sensitivity: Reacts quickly to lemons, onions, and tomatoes.
  • Purchase Warning: If you are not prepared to wash and dry this knife immediately after every use, please choose one of our stainless steel series instead.
  • Blade Steel: 3-Layer Japanese Blue Steel No. 2 (Aogami #2)
  • Hardness: 62–64 HRC (Vacuum Heat Treated & Deep Freeze)
  • Handle: Maple Wood + White Buffalo Horn
  • Blade Profile: 8.5-inch Bunka (K-Tip)
  • Use: Precision slicing, push-cutting vegetables, intricate tip work.
  • Series: Zhen (PM8M)
  • Model: PM8M-QF

Complete Your Collection

Pair with the PM8M 5" Utility Knife for a complete high-carbon precision set.

The Santoku, meaning "Three Virtues," is the master of slicing, dicing, and mincing. The Zhen Series 7" Santoku elevates this daily driver into a high-performance instrument. With a flatter profile than a chef's knife, it excels at vertical chopping motions and creating paper-thin vegetable slices.

Japanese Aogami #2 Core

At the heart of this blade is Japanese Blue Steel No. 2 (Aogami #2). Known for its high tungsten and carbon content, this steel reaches a hardness of 62–64 HRC. This extreme hardness allows for a steeper, sharper edge angle that stays sharp through effortless prep work. The core is sandwiched between softer stainless steel layers (San Mai), offering structural support while exposing the high-carbon edge for pure cutting power.

Nature Meets Craftsmanship

The handle is crafted from select Maple Wood, offering a smooth, warm tactile feel. It is capped with a premium White Buffalo Horn bolster. The light color palette of the handle provides a stunning contrast to the dark, reactive edge of the Blue Steel core.

⚠ IMPORTANT: High Carbon Steel Care

Please read before purchasing: This knife requires specific maintenance practices.

  • Not Stainless: The cutting edge contains no chromium and will rust if exposed to moisture.
  • Immediate Care: Wash and DRY thoroughly immediately after use. Never air dry.
  • Patina: Expect the exposed steel edge to darken and change color (patina). This is the mark of a true carbon steel blade.
  • Suitability: If you prefer low-maintenance tools that can be left in the sink, this knife is not for you. This is a tool for enthusiasts.
  • Blade Steel: 3-Layer Japanese Blue Steel No. 2 (Aogami #2)
  • Hardness: 62–64 HRC (Vacuum Heat Treated & Deep Freeze)
  • Handle: Maple Wood + White Buffalo Horn
  • Blade Profile: 7-inch Santoku
  • Use: Vegetable preparation, slicing meat, mincing herbs.
  • Series: Zhen (PM8M)
  • Model: PM8M-RS

FAQs

What is 14Cr14MoVNb powder steel?

14Cr14MoVNb is a powder metallurgy steel with high chromium (14%), molybdenum, vanadium, and niobium content. The powder steel process creates an extremely fine, uniform grain structure that allows the blade to be hardened to 62-64 HRC while remaining tough enough for kitchen use. It holds an edge 2-3 times longer than conventional VG10 and is the same class of steel used in knives costing $400+.
How hard is the Lan Series?

The Lan Series is hardened to 62-64 HRC through vacuum heat treatment. This is significantly harder than German steels (56-58 HRC) and harder than VG10 (60-61 HRC). The practical result is excellent edge retention. Most home cooks can go 6-12 months between sharpenings with regular honing. See our powder steel guide for detailed performance data.
Is the Lan Series harder to maintain than other series?

Harder steel does require a bit more care. Use a fine-grit whetstone (3000+ grit) rather than a coarse stone, and avoid ceramic honing rods which can chip the edge. A leather strop is ideal for daily maintenance. The trade-off is worth it: you'll spend far less total time sharpening because the edge lasts so much longer between sessions.
What handle does the Lan Series have?

The Lan Series features a hand-finished olive wood handle. Each piece of olive wood has unique grain patterns, making every knife one of a kind. Olive wood is naturally moisture-resistant and develops a rich patina with use. The ergonomic Western-style shape suits both pinch and handle grips.
Who is the Lan Series best for?

The Lan Series is built for cooks who prioritise edge performance above all else. If you find yourself sharpening too often, or if you want the closest thing to a professional-grade knife at a fraction of the price, the Lan Series delivers. It's also excellent for cooks who do a lot of precision work: the harder steel takes a keener edge for finer cuts.
