The easiest way to chop most herbs is with a large and sharp knife. You have much more control and it is quicker than using scissors (except in the case of chives). If you are chopping herbs in bulk, an Italian mezzaluna is a handy tool. This is a double-handed chopper with a semicircular blade that you use with a rocking motion. While these are usually single bladed, they may have up to four parallel blades that can make fast work of large piles of herbs.
