Overview
Slicing and chopping with this Kai Seki Magoroku Artisan nakiri relies on a straight single-layer stainless blade joined to a stainless handle. The seamless one-piece build is designed to be easy to clean.
A seamless, easy-to-clean stainless knife from a Japanese maker is the reason to consider it, and the edge geometry is aimed at low cutting resistance. The limitation is that it must be dried promptly after use to avoid rust.
Who it's for
Cooks who prep a lot of produce and want a wide, straight blade in a hygienic one-piece body get what they need. Shoppers after a knife that tolerates being left wet should look elsewhere.
Pros and cons
- Seamless one-piece body
- Single-layer stainless blade
- Three-step blade grinding
- Made in Japan
- Must be dried promptly
- Hardness rating not listed
- Handedness wording is garbled
Performance notes
The blade is ground in three steps so corners smooth out after the edge is applied, which cuts resistance when slicing. Because blade and handle are metal with no seam, dirt has no gap to collect in. Water and dirt left on the knife cause rust and discoloration, so it needs drying.
