Like, I get comments from people telling me it's weird I always try to peel potatoes like I am trying to make the worlds longest 1-piece potato peel. To me it feels way for efficient and fun to continu down a potato in 1 peel, while circling around it, instead of randomly scraping a hundred different pieces of peel off and having to reintroduce the cutter knife to the potato for every piece.
I bake with and can a lot apples -- an apple peeler is the fastest way to peel, core, and slice an apple.
It just comes down to having the space and "need" to justify buying one.
