This Y shaped Swiss peeler by Kuhn Rikon is incredibly comfortable to use and especially great at  attacking large quantities.  It even has a handy potato eye remover.  It's made entirely of stainless steel including the blades, is easy to clean, dishwasher safe and will last you a lifetime.

Personal gak staff testimony: "This peeler really is amazing, I've had one for over 15 years, it still looks great and the blades did not dull over the years.  It peels effortlessly.  You'll love using this peeler."
