I just got my skis sharpened for this season, and got out on the mountian and realized that it was realy hard to turn with sharp skis, because they were catching on everything. how do i fix this and dont just say get better.
 
slide some boxes, but not rails because yours edges might catch. or you can just ski on them and over time they will get less sharp.
 
yeah, boxes and skiing will dull them some, you can also run a file down the edge and round it a bit too
 
Go to your local chill ski shop or second hand sports store and use their grinder. 9/10 of them will say yes.

 
De tune at the nose and tail around the widdest part of the ski to make turning better, wont catch an edge so easily.
 
Gummy Stone if you want to dull them down a little and a file if you need to dull them down a lot. I only de-tune the middle half of my ski, I like to keep the rest of the ski somewhat sharp. Gummy stones are about $5-$10 and are the best for your edges, they don't damage the edge like a rock would.
 
if you dont have a gummy stone run a penny down it, it detunes but doesnt dull the edges too much
 
dosnt he just use a basic grinder that could be available at any hardware store? i didnt know that he was usin sumthin actually meant for ur skis.
 
just go to the side of the trail and run a rock along whatever part of the edge you feel is catching all the time. don't go crazy and detune them too much tho lol
 
there are some bad suggestions on this thread. a rock, really? hand-grinder?
here are some good suggestions:use a file to take off the edges on the nose and tail. take-off means place the file at a 45 degree angle to the edge and file it until it is round and dull.
if you do rails, do the same underfoot, where the rail touches the edges. you don't want to catch sharp edges on rails or boxes.
use a gummy stone on the contact points. gummy stones de-tune edges less than files, but, in my opinion, not enough to safely slide rails. (unless your a real baller, then use the file for the contact points, too)
if your on the hill and your edges are still too sharp, try a tree. the bark provides similar results to a gummy stone.

 
ding ding ding

gummy stones are pretty soft and only de-tune, they dont really dull. I use a diamond file and then the gummy stone.
 
just find something hard and rub it against your edges. not really rocket science. gummi stones are for removing burrs from when your skis hit a rock so i dont really know why everyone is telling you to use one of those.
 
look some youtube and then go to your local shop and ask if you can use a gummy stone. My shop will give them away once they get kind of small. then just firmly rub it from binding to binding. take in mind that you are trying to DE TUNE not DE STROY your edges.
 
yea, but when jumping u always want to have unsharp edges. then they wont catch if landing a little wrong.. they wont start carving out...
 
Guys Guys Guys, we could actually debate for months on this subject. Tuning ski' s is a very personal thing. ( taste wise ) and up to a certain limit.
 
Somethin smells wrong here. If u got a good tune then u turn / carve better and have grip on hardpak. U may have got a bad tune - this happens with both machine and hand tunes. The machine is out or the guy does something wack - something was overdone. Do both skis behave the same or is one worse than the other ? If only the tips or tail are catching then yeah - de-tune the 6-8 inches of tip with gummi, or stone sandpaper.

if the underfoot or if u are having trouble in snow doing spins, slides and slides on boxes your base bevel may be out. You need at least 1 degree if u are doing spins etc...Yeah race tunes are too much for slides and spins but it should get better as u use the ski. If is don't get better with wear/use the tune is out.

Yes a ski can be too sharp. Best thing to de-tune is hard gummi or fine diamond stone(about$19). Once u take down the edges with a file or make them 45 degrees u can't grow them back.... can't grind them back up if they are mutilated....bring the skis back to the shop tell them what's wrong.

 
I been racing for 13 years so I know one or 2 thing about skis. somthing you to know is you side edge is it can be cut at 3 diffrent angles. most twin tip are put on a 1-1 this means the side and bottom edge are 90 deagrees for ice put you edge are a 1-2 now there at a 45 degree angle and so on tyr messing around with that untill you feel comfortable with you ski.

I know I can't spell or write
 
I work in a ski shop and de-tuning consists of: 1.) get a metal file 2.) lay your skis on a flat surface with the bottom of the skis in the air 3.) (this is the hard step) best way to explain it is make a sandwhich with your file and the bottom part your skis so they're parallel to each other. what you need to do is slide the file towards the top of the ski (or in this case it's probably a twin tip so you'll need to do both) and find where the file is no longer parallel to the ski because it starts to U-out (the tip.) where it starts to create a tip is where you need to file. those are the sweet spots on the skis that will cause you to catch edges. otherwise if you feel the entire ski is catch everywhere, then file the entire edges down. when i say that i mean like 2-3 swipes with a file.

it's actually really hard to explain here but its very simple to do.
