Do you have a really good vegetable peeler, or just one of those cheap metal kinds, like your mother had when you were a kid?
Go dig it out of the drawer, right now, and see what you’ve got.
Does it look like this?

If your vegetable peeler doesn’t have a comfortable handle and a sharp blade that glides over the surface of whatever it is you’re peeling (without a lot of elbow grease from you), then you need to invest in a good vegetable peeler.
Trust me. You’ll be glad you did.

Try one of the new, broader stainless-steel peelers, like this one from Hoffritz, and you’ll easily peel potatoes, carrots, peaches, pears, and mangoes. You can also use the peeler to zest lemons, limes, and oranges, or use it as a cheese plane when you need a little shredded Parmesan to top a special pasta dish, etc.
You’ll find a wide variety of good vegetable peelers at fine kitchenware stores everywhere.
