5" Utility Knife - Zhen Series (PM8M)

ZHEN SERIES (PM8M)
5"
5.0 Stars  |  1 Review

The Zhen Series utility knife fills the gap between your paring knife and your chef's knife, the in-between blade that handles everything those two can't. A 3-layer Blue 2 (Aogami) carbon-steel core sits between SUS410 stainless cladding, hardened to 62–64 HRC and ground to 15° per side. Sized for sandwich meats, citrus, tomatoes, shallots and trimming work where a chef's knife is too long and a paring knife too short.

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
