The firmest option in Swix's rubber stone range, the Swix T995 X-Hard Rubber Stone is for edge work that calls for the stiffest compound. It deburrs steel edges and dulls the tip and tail on skis and snowboards. It rounds out an edge kit for tuners who want a full range of stone hardness.

Why we like it:

Having the extra-hard stone in the kit means you can match the stone to the job instead of forcing one stone to do everything.

Features and Functions:

Swix builds this extra-hard rubber grinding stone for tuning steel edges. Its main work happens at the front and rear of the ski or board, where it takes off burrs and puts a slight round on the steel. It's the hardest of Swix's three rubber stones, sitting above the soft and hard versions, and Swix lists it for alpine, snowboard, and rando use.

Bottom Line:

Add it if you already own a softer stone and want the full range. It's for tuners who like to pick the stone by the job.
