    Swix designed the Gummi Stone to remove nasty micro burrs that result after you sharpen your edges. Simply rub the Gummi Stone along the entire length of your ski or board's edge for a smooth finish. Or, just detune your tips and tails, which will reduce the chances of catching an edge, but will keep your side edges ultra-sharp for carving.
    • Grey stone is soft and works well for detuning tips and tails
    • Red stone is for polishing and light to medium edge clean up; can be used after filing to remove micro burrs.
    • White stone is for medium to heavy edge clean-up
    • Blue stone is extra hard for heavily burred edges
    • Item #SWI0115

    Gray Gummy

    • Familiarity: I've used it several times

    I like the shape and hardness of these stones. They feel easy to control in your hands while your using them and for me they work great as a rust remover and an edge tuner for finishing the edges after riding or sharpening.

    Great little helper

    • Familiarity: I've used it several times

    I ordered the red stone. Once I started to use it to finish edges, I realized how great it was. It brings the surface to a consistent bright finish, and makes me look like a pro tuner (at least to myself!). Pound for pound, the best tuning tool you can buy.

    Red Stone

    • Familiarity: I've used it several times

    I got the red stone and have found it to be quite effective for both removing burrs and polishing. Great all around stone. Easily fits in my pocket for on the mountain tuning


    • Familiarity: I've used it several times

    I'm sorry that I have gone so long through my life without having one of these. Works wonders getting the rust off. I did notice, though, that I wore a groove in it after just one use. Something to think about. I got the red one.

    Gummy Stone, bouncing here and there and everywhere. High adventure that is beyond compare. The gummy stone should not be rare. Buy two so you have a spare.

    Trusty Tuning Tool

    • Familiarity: I've used it once or twice and have initial impressions

    I used this gummy stone (blue) for the first time about a week ago and it works great for both removing rust and detuning. Definitely a handy tool to have in your tuning kit!

    The Gummy is your friend.

    • Familiarity: I've put it through the wringer

    Can't do a great tune without a gummy. I use them for part of the polishing process and for detuning the tip and tail.

    It is part of the process. I have my fresh gummies and I have my old gummies. As they wear out I pass them onto doing tip and tail detuning where they get the big V's in them.

    Gotta have one

    • Familiarity: I've put it through the wringer

    great for removing a little unwanted rust from your edges and for doing a little de-tuning. Everyone should own one of these if if they don't normally tune their own skis

    Red Gummy Stone

    • Familiarity: I've put it through the wringer

    Good for de-tune after a sharpen. I mostly use it for touch up work and keep it in my pocket to get rid of burs-n-stuff while I'm riding.

    Erase the rust

    • Familiarity: I've put it through the wringer

    Grab a red (or two) for a quick rust eraser and slight sharpen. If you're worried about messing with your edges, or don't have an interest in doing any substantial de-tuning/tuning, the red is where it's at.

    Love it

      I bought the red and grey stones for my tuning kit. The best part about this stones is that they are small enough to fit in your pocket. I've definitely taken the grey one with me on BC trips to de tune tips and tails if needed. Usually my friends end up borrowing it. The red one is great for cleaning edges and doing a quick tune.

      Great Little Stone

        I bought the "red" stone. Bought it for detuning tips/tails on my skis and helping removing rust. This thing is nice and small, feels good in the hand and easily removes blemishes and detunes the tips/tails. I'm glad I got the red color. Yes it does make a little bit of a mess but all gummy stones do. I really do love this little stone.

        These little guys are awesome

          After sitting all off season my skis had some surface rust and burrs from last season. Then I packed the skis on the roof and drove through the elements to Utah. Needless to say the skis didn't look so good when I got there. I picked up the red one and after putting in a little muscle into it this is what they looked like.. 3 year old Bacons and the edges look like new. Pretty awesome. Buy some!

          These little guys are awesome

          Gummi stones rock!

            The red gummi stone is swix's "medium hard" stone, with a softer grey, and harder blue also available.

            As such, this stone is the perfect middle ground. It's a must have if you're doing any kind of serious edge care.

            Since the picture doesn't show it too well, the stone is about 3 inches long and 1 inch tall.

            When to replace?

            I've been working a soft (gray) gummy to the core and figure it's probably time to replace. How far should one take a gummy stone before replacing it? it's still got surface that feels gritty, so I figure why replace it? I mostly use to detune and it still seems to work for that.

            I want to detune my snowboard. Would the Gray or Blue be better?

            It says the Gray would be better in the description, but it seems like the harder blue stone would be better because in detuning you really wanna take down your edges.
