If you’re a fan of electric knife sharpeners, this new AngleSelect Sharpener from Chef’s Choice will be a must-have. It sharpens both European and Asian-style knives, which have different blade angles: European knives traditionally have a 20-degree edge, while santoku and other Asian knives have a 15-degree edge. There’s a spring-guide system that helps you draw the knife across the diamond abrasives at the right angle. The Chef’s Choice Model 1520 retails for $170 atCutleryandmore.com.
