Best thing: Very sharp 15° results

Honest catch: Expensive for an electric sharpener

Our verdict

If you want the sharpest results an electric sharpener can give — and you are happy with 15° edges on all your knives — the 15XV is the premium choice. The trade-offs: it costs about twice as much as basic electric sharpeners, and diamond stages remove more metal than a gentle hone, so use the first stage only when a knife is truly dull.

The 15XV is Chef'sChoice's flagship home sharpener and a long-time pick for cooks who want a truly sharp edge without a whetstone. Its three stages build a triple-bevel Trizor XV edge: medium and fine 100% diamond abrasives shape and sharpen, and a patented stropping stage polishes. Flexible spring guides hold the angle from heel to tip, and it converts traditional 20° factory edges to sharper 15° ones. It works on straight and serrated blades and carries a three-year limited warranty.

Why you’ll like it
