Thanks to a spring-loaded lid, six knife-sharp blades rotate down at 51 degrees to precisely chop any type of fruit, vegetable, herbs or nuts. Sharp 18/10 stainless-steel blades. Chopped items stay contained to minimize clean up. Snap-on lid creates safe storage for chopper blades. Great for keeping hands clean and odor-free when you're chopping onions and garlic. From the German company Rosle, manufacturers of quality kitchen tools since 1903. Dishwasher safe.
