Edge retention
- What we look at
- How long a blade stays usable through ordinary cooking before it needs honing or sharpening, and how easy it is to bring back once it dulls.
- How we check
- We cook with it: onions, herbs, tomatoes, squash, proteins. We pay attention to how the edge feels over weeks of regular use, not on the first day. For boards, we look at whether the surface is kind to an edge or dulls it.
- Why it matters at home
- A knife that is sharp on day one and dull by week two is a knife you stop using. Edge retention decides whether a blade is a tool or a drawer ornament.
