Brand new from Swix, the Evo Pro Edger is a relatively affordable electric side edge sharpening tool. If you're looking to put the ultimate edge on a pair of skis this puppy will do it, and with very little effort on your end. It uses a circular diamond disc to sharpen and hone your edges quickly and easily. Adjustable in one-degree increments from 90° to 85°. The diamond disc is backed by a steel spring which ensures consistent pressure regardless of stone wear or overzealous use. The disc rotates in the direction of the sidewall of the ski (instead of toward the base) this eliminates to possibility of creating a hanging burr.
