Used mainly by butchers and Chinese cooks, a cleaver is an axlike cutting tool. Its flat sides can be used for pounding, as in tenderizing meat. Cleavers are usually heavy for their size, but evenly weighted. A good cleaver can cut through bone just as easily as it can chop vegetables. The butt end can be used as a pestle to pulverize seeds or other food items; the flat side is also great for crushing garlic.
