Best way to peel potatoes and other vegetables are these little bastards.
Well, there is a variety looking like normal knife with slots in the middle, but it sucks. Get this Angry Birds like variety, where you pull the blade like your Gillette shaver, not push it like a knife. They come with metal and ceramic blades. Metal blades usually have saw-like teeth to lengthen cutting edge. This shape also makes the blade self-sharpening, almost like a katana. So let’s try out the metal one first. Cuts good. Now let’s try the ceramic one. Also good. But personally, I prefer the metal one. The peels are thin, but thick enough to remove all the dirt.
