The Swix Helium Vise is a two-piece lightweight economy ski vise that gives you two angles for side edge positions, set at 60 and 90 degrees. With the 60 degree side edge you will have better control for side edgework. If you want crisp sharp edges set the Helium Vise to 90 degrees. The Helium Vise is for use on freeride and alpine skis and is based upon rubber friction. Best of all the Swix Helium Vise is lightweight and compact.
