If you use an apple peeler it maybe because you have an awesome (or without one, awful) amount of apples to peel.
Our red and white one, and similar equipment from people like Starfrit, comes with 3 spare blades.
When these run out, it is easy to go spare.
Unnecessary!
If your machine looks like our picture (not Apple Pro Peeler), these spare blades come in a replacement pack of three.
