Instead of enlisting an army of specialized knives for slicing, dicing, wedging and coring fruits and vegetables, use this one easy-to-operate tool. Professional Multi-Chopper is an indispensible kitchen assistant sold exclusively by Williams-Sonoma. Mix and match its three pushers and four interchangeable blades to prepare everything from apples to carrots to onions. Insert the correct blade, then push down firmly on the spring-loaded lid, and it cuts whole fruits and vegetables and deposits slices into a removable, closed container.
