The quick answer: If you want sharp kitchen knives in under two minutes without learning whetstone angles, the Chef'sChoice 15XV Trizor XV is the best full-featured electric knife sharpener for serious home cooks, while the Work Sharp Culinary E2 is the best budget-friendly ($50–$65) electric sharpener for everyday beginners.
Top Picks: Best Electric Knife Sharpeners
Modern electric sharpeners fall into two clear groups: multi-stage diamond machines that reprofile and polish 15° or 20° bevels, and compact flexible-disc machines with automatic timers that prevent beginners from over-grinding.

1. Best Overall: Chef'sChoice 15XV Electric Knife Sharpener
If your kitchen drawer holds a mix of Western chef's knives (like Wüsthof, Zwilling, or Victorinox) and thinner Japanese-style blades (like Shun, Global, or Miyabi), the Chef'sChoice 15XV is the gold standard countertop machine.
- Why 15 degrees matters: Most older electric sharpeners grind a blunt 20-degree edge. The 15XV uses three progressive stages of fine diamond abrasives to create a triple-bevel 15-degree edge that slices tomatoes and meats with noticeably less force.
- Who it fits: Home cooks who sharpen 4 to 10 kitchen knives regularly and want fast, repeatable results without clamping rods or soaking stones.

A countertop electric sharpener for home cooks who want fast, repeatable results and do not want a sharpening hobby.
- ✓Three-stage electric sharpening path
- ✓Diamond abrasive stages
2. Best Under $65 for Beginners: Work Sharp Culinary E2
Not every beginner wants to spend $160+ on a heavy countertop machine. The Work Sharp Culinary E2 solves the two biggest fears new users have with electric sharpeners: spending too much money and accidentally grinding away too much steel.
- Flexible abrasive discs instead of rigid grinding wheels: Similar to miniature belt/disc sanders used by knife makers, flexible discs conform gently to the edge rather than gouging the blade.
- One-button timed cycle: Press the button, pull each side of the knife slowly through the 20-degree guided slots until the machine automatically stops (about 45 seconds), then finish with 3 light strokes in the center ceramic honing slot.
- Bonus scissor guide: Pop off the magnetic knife guide to sharpen dull kitchen shears in seconds.

- ✓One-touch timed cycle stops automatically when done
- ✓Flexible abrasive discs remove less metal than harsh grinding wheels
Who Should Skip an Electric Knife Sharpener?
Even the best electric sharpeners have tradeoffs you should know before buying:
- Skip electric if you want custom angles (15° to 30°): Electric slots lock you into one fixed angle (15° on the 15XV, 20° on the E2). If you want to dial in exact angles for both pocket knives and kitchen knives, buy the manual Work Sharp Precision Adjust guided system ($55–$70) instead.
- Skip electric for single-bevel or high-end artisan knives: Traditional single-bevel Japanese knives (deba, yanagiba) or thin handmade carbon-steel knives should be sharpened on a 1000-grit whetstone like the Shapton Kuromaku 1000.

- ✓Repeatable 15 to 30 degree angle range
- ✓Includes coarse, fine, and ceramic sharpening surfaces
Common Mistakes and Maintenance Cost
Ongoing maintenance cost on electric sharpeners is low, but replacement abrasive discs (on the Work Sharp E2) or diamond dressing eventually apply after years of heavy household use. To make your knives and sharpener last:
- Do not use Stage 1 every week: Stage 1 removes steel to rebuild a dull bevel. Once your knife is sharp, use only the polishing/honing stage (Stage 3 on the 15XV or the ceramic slot on the E2) for routine touch-ups.
- Never press down into the slots: Downward pressure stalls the motor or creates an uneven wave in the blade edge. Let the spring guides support the blade and pull at a steady 1-inch-per-second pace.
- Wash and dry knives before sharpening: Food grease clogs diamond wheels and flexible abrasive discs quickly.
