Why you would want to take the peal off your apples and potatoes is beyond me. the flavor, fiber and other nutrient are in there and doing so is tantamount to processing it. That being said, you might as well do the unthinkable in style. Enough about my opinions on the outer layer. People people stuff, duh.
The Victorio apple and potato peeler can quickly peel, core and slice with a few turns of the handle. Remove the coring blade and peeling potatoes is a snap. The unit is sturdy enamel-coated cast-iron and all the stainless steel blades are adjustable and replaceable. It will last for years even with heavy use (5-year warranty included). To keep things sturdy, a strong suction base keeps unit firmly in place on smooth non-porous surfaces. There’s an available clamp-based model as well. All this for a hair less than $20.
