Knife Sharpeners

Owners overwhelmingly love how sharp and quickly the Trizor XV gets their knives, often calling the results sharper than a professional and praising how simple and nearly foolproof it is to use. The main trade-offs are the high price and that it grinds edges down to a narrower 15-degree angle, which removes metal and isn't to every cook's taste.

Owners consistently call this one of the fastest ways to get a knife razor sharp, taking a dull or even damaged blade to a shaving edge in just a few minutes with little skill required. The belt system puts on a durable convex edge and handles everything from kitchen knives to axes. The trade-off is that it removes metal aggressively and can overheat, scratch, or round tips, so most owners stress using slow speeds and practicing before trusting it on a favorite blade.

The Lansky Deluxe 5-Stone is an affordable, beginner-friendly kit whose angle guides help newcomers hold a bevel, and patient owners get shave-sharp results that can last for years and rescue badly damaged edges. But it's a mixed bag: many call the clamp squishy and loose, the setup slow and finicky, and matching the angle tough on a lot of knives. Several hit harder problems too, including brackets that bend or snap, stones striking the clamp on small blades, and weak performance on super steels.
