Mezzaluna

A mezzaluna is a knife consisting of one or more curved blades with a handle on each end, which is rocked back and forth chopping the ingredients below with each movement. They most commonly have a single blade, but are sometimes seen with two or three blades.

It is typically used for mincing herbs or garlic, but it can be used for chopping other things such as cheese or meat. Very large single blade versions are sometimes used for pizza. Common uses in Italy include preparation of a soffritto or a pesto, etc. In countries like Egypt, Jordan, and Palestine, it is used to chop mulukhiyah.

Name
Mezzaluna means 'half moon' in Italian, after the curved shape of the blade, and is the most common name used in the UK. Other names used include herb chopper, hachoir, (from French), makhratah (from Arabic), and  (from Yiddish).

Cutting board
Mezzalunas may be found sold with a cutting board that has a shallow indentation in it, marketed as a herb chopper.
