Dear Kitchen, I realized this weekend as I was peeling a sweet potato, that my vegetable peeler is totally dull. Is it possible to get them sharpened or should I just toss it and get a new one? It's not that I don't want to spend the money, but it seems strange that they would be disposable. Cheers, Eliza Kyocera ($17.95). It has a ceramic blade that will stay incredibly sharp for, I'm told, 20 years. Oxo also makes a highly rated version, the I-series Swivel Peeler, ($7.99) which has blade that can be replaced when it gets dull. Hope that helps.
