Overview
Not everyone needs (or wants to pay for) an electric knife sharpener. The Chef’sChoice 4643 AngleSelect Manual Sharpener brings the same diamond abrasive technology and dual-angle support as the flagship 1520 — in a compact, no-power-needed package at $67.99.
3-Stage Manual Sharpening
Just like its electric counterpart, the 4643 uses three stages:
- Stage 1 (15°): Diamond abrasives for Japanese-style knives
- Stage 2 (20°): Diamond abrasives for European-style knives
- Stage 3 (Polish): Specialized diamond abrasives for a refined, polished finish
Pull the knife through each slot 3-5 times and you’ll feel the difference immediately.
Compact & Portable
At roughly the size of a stapler, the 4643 fits in a kitchen drawer, a camping bag, or a boat galley. No cord, no outlet, no setup — just grab it and sharpen. This makes it ideal for travel, outdoor cooking, or small kitchens.
Diamond Performance
Same 100% diamond abrasives as the premium electric models. These cut through any knife steel — stainless, carbon, high-alloy — without glazing or wearing out like ceramic alternatives. The precision angle control guides ensure consistent results even for beginners.
Electric vs Manual — Which to Choose?
- 1520 Electric ($224.99): Faster, more polished results, better for large knife collections
- 4643 Manual ($67.99): Same technology, portable, 1/3 the price, great for 1-5 knives
If you sharpen knives weekly and own 10+, go electric. For occasional sharpening or travel, the 4643 is the smarter buy.
Verdict
Rating: 4.4/5
The Chef’sChoice 4643 delivers 90% of the electric 1520’s performance at 30% of the price. Diamond abrasives, dual-angle support, and zero-power portability make it the best manual knife sharpener we’ve tested.
