Edge lsoing sharpness

post #1 of 5
Thread Starter 

I am wondering how fast you guys are finding your edges are getting dull.  I am on slalom skis and after two days of skiing the things are done.  It seems I need a file; diamond stones will not cut it (no pun intended).  It is a particularly interesting year here in New England.  All man made snow and it gets scraped down pretty fast to the bomb proof base.  We average 16K to 20K of vertical each day.  Skis are not going to last many years at this rate :)  Pete

Have you knocked the diamonds out by excessive pressure?  Use a lube sold for ski sharpening and no more than moderate pressure on the stone/file.

 

When filing, I use ski-specific files.  I ink the edges with a felt tip marker, then just remove enough steel to remove the ink and get a sharp edge.  Any more steel removal than that needlessly shortens the life of the ski.  Always use a file guide.

New England ice, especially ice with dirt mixed in just kills edge sharpness. I'm sharpening my edges every day this season. They just won't hold up with the conditions we have this year.

 

If they are really dull, and it is going to take too many passes with a stone to get the edge back, you will have no choice but to take a file to them. As long as the edges are not too damaged, a fine file should work after a few passes, Buy a high quality file, the cheaper ones just wear out fast, and you end up spending more money in the long run.

 

Unless you spend the money on a carbide file (they are almost as hard as a diamond stone), I would make a pass with a coarse diamond stone to knock down any case hardened burrs before filing. Hardened edges will take the life out of a steel file very fast.

Thanks for the answers. 

 

I do use ski specific files,  fixed guide (87), a magic marker etc.  I am having the same experience as CK.  I have been much more focused on keeping my edges sharp this year because my concentration has been on carving.  Coupled with these umm, "firm" conditions, it just seems that a pass with fine file is required to bring the edges back more often than not.  

 

The interesting thing about this season has been that it it is great for learning very good skiing habits.  I still blow out at times on glare ice, but I am getting close to figuring it out :)

What brand ski are you using?  Most manufactures are using a 50 hardness on the Rockwell scale steel for their edges some may even use a 60 hardness but they are few and harder to sharpen.   If you are using an edge guide set at 87 degrees, that should hold an edge at least three days unless you are skiing on rocks.  The 1 - 3 grind that you are talking about is an aggressive grind maybe you should try the 0 - 3 grid.  The flat bottom may make the ski more difficult to swivel a turn but you said that you are trying to carve more of your turns.  When toughing up the edge I would focus more on the side edge than on the bottom part of the edge.  Also a stone is a better choice to do daily work.

 

Good Luck
