The Chef'sChoice 15XV EdgeSelect is a premium 3-stage electric knife sharpener designed to convert standard 20° factory edges into the brand's proprietary 15° Trizor XV edge. It uses 100% diamond abrasives in stages 1–2 for aggressive sharpening and honing, with a patented flexible stropping stage (stage 3) for polishing and serrated blade support.

Best for: Home cooks and culinary enthusiasts who want fast, hands-free sharpening with minimal technique. The spring-guided slots handle both straight and serrated blades automatically.

How it works: Drop a blade into the appropriate slot, press the power button, and draw the knife through in ~1 minute for initial sharpening or ~10 seconds for maintenance. The 15° angle is fixed and optimized for Western kitchen knives.

Trade-offs: At ~$166, it's a premium-tier electric sharpener and removes significantly more steel than a whetstone, making it less ideal for prized Japanese or heirloom blades. Purists argue the fixed angle and aggressive abrasives sacrifice edge durability compared to whetstones. However, Chef'sChoice's 3-year warranty and decades of kitchen-pro adoption offset these concerns for most home users.
