With this hand-operated machine, in one easy motion you can pare (peel), core, and slice apples. It's also ideal for use with pears and potatoes. The machine is capable of three separate functions: paring, coring, and slicing; coring and slicing only; or paring only. The thickness of the slices are approximately ¼" wide. Use it to create curly fries or chips-on-a-stick using russet or sweet potatoes or quickly create onion twists to deep fry, make French onion soup, or to garnish a steak or hamburger. The machine suction mounts to smooth surfaces and releases with a lever on the side; a c-clamp is included for porous surfaces, that extends for counters up to 1½" thick.
