SHAN ZU 20 cm (7.9 in) chef’s knife, 67-layer review

A 20 cm (7.9 in) Damascus chef’s knife that publishes everything that matters: a Japanese 10Cr15MoV core at a stated 62 HRC, 67 forged layers, and an explicit statement that the pattern is not etched.

What we would actually buy The most completely specified Damascus knife in this catalog, and not the most expensive. That is the right combination.

What you are getting

A 20 cm (7.9 in) Damascus chef’s knife with a Japanese 10Cr15MoV core stated at 62 HRC, clad in 67 forged layers, with the maker stating the pattern is not laser-etched.

Why this listing is the model

It names the core, publishes the hardness, gives the layer count, and addresses the etching question directly. Four things, and most Damascus listings give one.

What 62 HRC means for you

Long intervals between sharpenings, a keener edge than any European blade, and a hard rule: no bones, no frozen food, no glass or stone boards. Hone on ceramic, sharpen on a stone.

Against the dearer knives here

The Wakoli and Minamoto Zen entries in this hub are three-piece sets, and both use a VG-10 core at a stated 60 HRC. This is a single knife with a harder stated core at a lower price.

Availability

  • A 20 cm (7.9 in) chef’s knife at the middle of this hub, not the top

Compromises

  • 62 HRC chips on bone and frozen food
  • Needs a ceramic rod and a stone, not a steel or a pull-through
  • No edge angle published

The questions that come in

Is 62 HRC too hard for a home kitchen?

It is hard. It holds an edge far longer and chips where a 56 HRC blade would roll. Keep it for boards and away from bones, and it is a pleasure.

Can I hone it on a normal steel?

No. At 62 HRC the steel is softer than the blade and slides over the edge. A ceramic rod is the correct tool.
