Equipment Review: Best Electric / Manual Knife Sharpeners & Our Testing Winners
Professional ZoneEquipment & Tools/America's Test Kitchen/4:22
Your knives are only as sharp as your worst day allows, and most electric sharpeners turn good steel into expensive scrap metal faster than a new extern can burn a pan. America's Test Kitchen puts both electric and manual systems through the kind of testing that matters — repeated use on actual carbon and stainless blades, not just the marketing claims. Anyone who's watched a line cook try to brunoise with a dull Wüsthof knows that proper edge maintenance isn't optional equipment.
