What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the Chef'sChoice 1520 is the other electric machine carrying genuine high-trust backing. nytimes.com's reviewers describe it as 'reliable, fast, and simple to use,' noting you can choose between a 15- or 20-degree angle and that it 'quickly turns out a razor' edge. Consumer Reports' praise for the closely related Chef'sChoice diamond-abrasive platform reinforces the brand's standing for guesswork-free, angle-controlled sharpening.

As with its sibling, the specialist communities add friction. r/Cooking commenters call it 'the absolute bees knees' and report knives 'sharper than new,' while r/sharpening and r/chefknives reviewers caution that these machines remove more material than necessary and offer less flexibility between heavy repair and fine polishing. The advice to keep it away from Japanese knives recurs here too.
The synthesis: positioned as the dual-angle electric workhorse, it satisfies the high-trust labs and most casual users, with the same trade-offs every electric pull-through carries — speed and consistency at the cost of metal removal and refinement.
- ANGLESELECT – Applies a traditional 20 degree edge or a finer 15 degree edge for precision slicing
- 100% diamond abrasives for sharpening and honing
- DIZOR ENGINEERED– 2 distinct facets set at different angles that form a longer lasting, arch-shaped edge
- PRECISION ANGLE GUIDES - Ensures accurate sharpening throughout the entire edge and eliminates any guesswork
- SHARPENS MOST KNIVES – Sharpens straight edge and serrated knives
