Because it employs six blades instead of one, this hand-powered machine works much quicker than a single knife blade and makes it unnecessary to bring out a food processor for a small chopping task. Perfect for onions, hard-boiled eggs, cheese, nut, and herbs, the chopper comes with a base to contain food, or it can be used on any cutting surface without the base. Pressing down the machine's knob plunges a wave-shaped stainless-steel blade, and each time the spring-loaded plunger springs back the blade rotates a little so chopping is uniform and thorough. Housed in rugged, transparent plastic, the chopper stands 9 inches high. One of Tupperware's handy food-preparation tools, the chopper is dishwasher-safe and carries a 90-day guarantee against defects.
