How to Choose an Electric Knife Sharpener
Stages
Coarse stages repair dull edges, while fine and stropping stages polish. Two stages suit most homes; three stages give a finer finish.
Angle
Western knives use about 20°; Asian-style knives use about 15°. AngleSelect-style sharpeners handle both.
Abrasives
Diamond abrasives sharpen quickly; belt systems like Work Sharp adapt to any blade.
Serrated knives
Not every sharpener handles serrated blades; check the listing if you need it.

Do electric sharpeners damage knives?

Every few months for most home cooks; hone in between.
