Chef'sChoice Trizor XV Review

Most electric knife sharpeners are how good knives go to die — cheap grinding wheels that tear a rough edge and eat the blade. The Chef'sChoice Trizor XV is the exception people who know sharpening will actually recommend, for a specific job: fast, hands-off, repeatable edges on tough Western knives, with no skill required. It's a strong option in our best sharpening systems roundup — with real caveats.

What the spec sheet tells you

It's a motorized, three-stage diamond system with a fixed 15°-per-side geometry — and that fixed angle is the clever part: it re-profiles a factory 20° German edge down to a keener 15°, which genuinely cuts better afterward (more on why in knife sharpening angle). The three stages run coarse and fine diamond, then a stropping/polishing stage for a refined finish. Dull to sharp takes a couple of minutes with no technique at all.

How it performs — and the big caveat

Genuinely fast and repeatable; it scores a 10 on ease of use for a reason. Feed the knife through the stages and you get a keen, consistent edge every time — no burr-chasing, no wandering angle. The unavoidable cost is metal: motorized diamond wheels remove far more steel than any manual method, so every sharpening takes a real bite out of the blade and shortens its life. And the fixed 15° geometry that helps a German knife will ruina hard, thin Japanese blade or a single-bevel knife — it's the wrong tool for those entirely.

Who it's for

A busy household with a drawer of tough Western knives (Victorinox, Wüsthof, Mercer) who want them sharp with zero skill and don't mind that the sharpener is bulky, noisy and pricey. For that use it's excellent. It is emphatically not for anyone who owns nice Japanese knives, or who sharpens infrequently enough that the metal loss matters — on a $150 gyuto, electric wheels are expensive damage.

Value

It's the priciest tool in the sharpening roundup, and the value depends entirely on the fit. For a busy Western-knife kitchen that would otherwise never sharpen at all, a fast electric that keeps everything keen is worth it. For a cook with good knives or a bit of patience, the money is better spent on a guided system (which removes far less metal) or a stone — see the trade-offs in whetstone vs electric sharpener.
