We like the Swix Phantom Edge File Holder about as much as we like a smooth carve down recently groomed corduroy, and when it comes to carving corduroy, the smoother our ski edges the better. This handheld multifile switches between six angles to accommodate all sorts of skis from powder planks to cross-country sticks. A little bit longer than most handhelds, the Phantom Edge File Holder gives a good grip and better stability to keep our edges as straight as the lines we dream of shooting.
