There are many different electric and manual curly fry potato cutters available with a wide range of features, such as swivel handles, push handles and different-sized blades. Some potato cutters are also able to cut other vegetables and fruits, including apples, zucchinis and radishes.
The size of the blades on the potato cutter determines the thickness of the potato fries. Some potato cutters come with multiple blades of varying sizes to cut potatoes into thin or thick fries. Unless recommended by the manufacturer, sweet potatoes are often too dense and hard to pass through the blade, which can result in a damaged blade.
