Apple Parer-Slicer -- Clamp-on Base. Same great tool as Suction-base model. Attaches to work surface by tightening screw-clamp, similar to a C-clamp. Quickly pare, core and slice apples all in one easy operation with minimal waste. The fruit is left in a spiral form, which with one cut of a knife will transform into small ring slices that are just right for canning, sauces, pies, dehydrating and other delicious apple treats.
