Description

One step closer to your own full-service shop.

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

Rust-be-gone

  • 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.

Bu-Bye Rust

  • Familiarity: I've put it through the wringer

A must-have for your tuning kit. Works wonders on my edges. Smooth's them out and takes the rust away just like that.

Bye two, or three

Dashing and Daring

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

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.

Red Gummy Stone

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

  • Gender: Male
  • 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!

grab a couple

Grab one of each color (hardness) and use them as a system to prep and maintain your edges. They make for a great recovery tool after poor care leaves little rust spots on your skis (red one).

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.

Best Answer Responded on

Gray. The gray does a very good job of quickly dulling that edge as it has a good grit and the softness lets it kind of conform to the edge (putting more surface in contact).

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.

Good ol' Gummi Stones, work like a charm

These really do there job; removes all those nasty little burrs that cause your face to smack to the ground after you tried to de-tune or tune up those edges. Lasts a very long time. Dont use inside though, little particles fall off when gliding across the edges. Save yourself some pain and get one.
