Skiers who want a firmer deburring stone than the soft version will reach for the Swix T994 Hard Rubber Stone. It's a rubber grinding stone for steel edges, built to clean up burrs and take the sharpness off the edge near the front and back of skis and snowboards. Edges come out cleaner, and tips and tails engage more smoothly.

Why we like it:

It's the middle option in the range, which makes it the one we'd start with if you're only buying one rubber stone.

Features and Functions:

Swix makes this rubber stone in three hardnesses, and the hard version sits between the soft and extra-hard stones. It's meant for tuning steel edges, with the main jobs being burr removal and rounding the steel at the tip and tail of alpine skis and snowboards. Swix also lists it for rando, so it belongs in a touring repair kit too.

Bottom Line:

This is the all-purpose rubber stone for keeping edges burr-free between full tunes. Racers, all-mountain skiers, and riders will all get use out of it.
