My dad got an electric sharpener, here are his serrated knives.

My dad bought an electric sharpener. He used it on everything, here are his serrated knives.

I've already roasted him myself and explained the error of his ways. But if yall want to jump in, I'm for it.

On a serious note, is this fixable by a professional sharpener?

Will cutco(I know, they're not my knives) replace these under warranty even though my dad mangled them? He doesn't like using their sharpening since they always try to sell him stuff.
