Trizor XV / 130 Professional Electric Knife Sharpener

Last verified May 12, 2026 by the Lifetime Picks Editorial Team

Chef's Choice's professional electric sharpeners are the consensus pick for home cooks who want a sharp knife but won't commit to whetstones. The three-stage system uses progressively finer diamond abrasives (coarse → medium → fine stropping), and the spring-loaded guides hold the blade at a consistent 15° or 20° angle — eliminating the freehand-skill barrier that keeps most people from sharpening. America's Test Kitchen has used Chef's Choice as their electric reference for over a decade. r/Sharpening warns that any electric sharpener removes more steel than a whetstone (so over 20+ years you'll grind through a knife) — but for home cooks who replace their chef's knife every 10-15 years anyway, that tradeoff is acceptable. Wüsthof, Henckels, and Mercer specifically test compatible with this model.
