Every kitchen needs a vegetable peeler and there are two types available swivel peelers and y-peelers with the swivel being the most popular.
Swivel peelers have a vertical blade that is used by moving back and forth.
The Y-Peeler has a horizontal blade and is used by starting at the bottom and peeling the skin towards you, which some find a bit tricky. I just love y-peelers for creating gorgeous vegetable ribbons for my salads.
Julienne peelers are a cheaper alternative for creating vegetable "spaghetti" if you are keen on avoiding gluten and wheat products, they also make your salads a lot more interesting.
Even though there is some food wastage you can get around this by bagging and freezing the leftover vegetable bits for use in stocks and soups.
