There are different opinions concerning using a peeler on Shabbos.
In general, the custom in America is to use a peeler, certainly where the peel is edible, whereas the custom in Israel is not to use it.
It is generally permitted to peel fruit on Shabbos because peeling fruit is considered preparation for eating, and not an act of forbidden separation.
However, it is not permitted to use a utensil that is made for acts of borer, and because a peeler is made specifically for peeling (which is forbidden unless done as preparation for immediate eating – see Mishnah Berurah 321:84), many forbid using a peeler (see Machazeh Eliyahu 51; Biur Halachah).
Yet, many are accustomed to peel with a peeler on Shabbos, because it is viewed as a sophisticated knife and not an item specifically used for borer. Furthermore, a number of authorities maintain that the entire melachah of borer does not apply to peeling (see Aruch Hashulchan 319:22; Rabbeinu Chananel likewise writes that borer does not apply to peeling).
In practice, see Shemiras Shabbos Kehilchasah 3:34, who permits the use of peelers for peels that are generally eaten with the fruit, because they are considered part of the fruit; She’arim Metzuyanim Behalachah (80, K.A. 24) is more lenient and permits the general use of peelers.
