How We Chose the Best Knife Sharpening System
To build this guide to the best knife sharpening system, we compared knife sharpeners sold on Amazon US, including electric, manual, pull-through, guided and honing-rod designs, by abrasive type, angle options, stages, build quality and price. We then read patterns in verified-buyer reviews for edge quality, metal removal, ease of use, durability and how each sharpener handles Western, Japanese and serrated knives.
Clean blades after sharpening to remove metal dust before they touch food, following USDA Food Safety and Inspection Service cleanliness guidance. Our method is explained on the How We Test page; this is a research-based guide, not a lab test.
