Serrated peelers are designed to safely peel the skin off of fruits and vegetables that are soft with thin skin.
A serrated blade edge allows peeling to occur with significantly less pressure. The serrated type of peeler works great with soft foods and with it you can peel a tomato, peach, kiwi or plum just as confidently as you can peel a potato with a potato peeler.
If you were to try to peel a tomato with a potato peeler it just wouldn't work well, if at all. The softness of the tomato and the smoothness of the potato peeler blade just wouldn't allow it to "catch" onto any skin without basically destroying the tomato by pressing hard.
A serrated peeler is the right tool for peeling tomatoes and many other foods.
This is a type of specialty peeler.
It can be bought by itself, but it often makes sense to buy a serrated peeler as part of a set.
Getting a set of peelers often is much cheaper and it also provides other specialty peelers and even backup regular peelers.
Even upscale quality brands like Oxo provide peeler sets.
