Of the many peelers I have used so far, the one I recommend is the Kai-branded T-shaped peeler.
Some overseas peelers have a sharp edge, but many of them are slippery, scary to use, and the price is quite high, so they are short in obi and long in sashes. The T-shaped peeler is sharp and fits well in the hand. Unlike other peelers, it has an asymmetrical shape with a diagonal blade and a non-slip handle shape.
Using this will increase the amount of vegetables used in cooking and make cooking very healthy!
