The Mezzaluna Folding Herb K nife with integrated blade guard is from Joseph Joseph. The name of this accessory is Italian for crescent and this is the shape of the blade, which, moved by its two handles, will quickly and easily, and most importantly finely, chop par sley and dill as well as basil, mint and coriander. The handles of the knife are folded away after use to form a blade sheath, which not only saves space in the kitchen drawer, but also guarantees safe storage.
