A cook or chef's knife as claimed by the manufacturer. There's no clear definition between the two categories, with each available at a variety of price points. Though not entirely meaningless, they're usually interchangeable terms, and 'chef' doesn't necessarily mean better quality.

We recommend kitchen knives with a CHOICE Expert Rating of 80% or more.

CHOICE Expert Rating View more details.

This CHOICE Expert Rating is made up of cutting performance (70%) and sharpness (30%).

Cutting performance score View more details.

We assess the knives' performance by slicing and dicing various foods including tomatoes (full slices), carrots (julienne), onions (half-moon slices) and steak (diced).

Sharpness score View more details.

Made up of the initial sharpness score (30%) and sharpness after blunting (70%).

Initial sharpness score View more details.

An external specialist laboratory assessed the knives for their sharpness when new and unused. The higher the score, the sharper the knife.

Sharpness after blunting score View more details.

Each knife is subjected to three cut depth tests with two 50-cycle burnishing processes in between them,slicing strokes into a galvanized steel rod using a purpose-built mechanical burnishing machine. Models with higher scores are more resistant to blunting from repeated use.

Shop Ethical rating View more details.

Shop Ethical rates the environmental and social impact of the company (not the product) using independent sources. This rating is not included in our total score. The rating ranks from A (highest) to F (lowest); N/A means there is no rating for that company.

The back of the blade adjacent to the handle in centimetres. This is the strongest part of the knife and it’s proximity to your hand makes it ideal for tough cutting.

4.5
Rockwell hardness rating View more details.

A unit of measurement used for calculating a material's hardness, as claimed by the manufacturer. A higher rating helps retain edge sharpness for a longer period of time but this also leaves the knife prone to damage as it increases the brittleness. A lower rated knife may last longer but will need to be sharpened more often.
