7" Santoku Knife - Zhen Series (PM8M)

ZHEN SERIES (PM8M)
7"
5.0 Stars  |  1 Review

The Zhen Series santoku is a nimble Japanese-style all-rounder built around a Blue 2 (Aogami) carbon-steel core. A flat-ish profile and tall blade suit push cuts, fine slicing and the quick scoop-and-chop most home cooks reach for daily. Three-layer San Mai construction wraps the hard carbon core in SUS410 stainless cladding, and the blade is taken to 62–64 HRC for a hard, keen edge. Maple wood and white buffalo horn finish the octagonal handle, set on a hidden tang (a partial tang).

DESCRIPTION

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
