I'm a ski race parent. I tune every couple of days on snow. My U12 boy skis on 0.5 degrees base bevel, three degrees side edge. Here he is on a firm course at his last race this year: https://youtu.be/RWYO2ib-qe8?si=CRH01ViFUFApSx_o Setting that up is difficult but it's pretty easy to maintain once it is there. Side cut.com has great advice and tools. If you are on groomers and ski on decent skis, not powder boards,…

Do you mean .5 or 5 for the base bevel? 5 is quite far off the snow.

Yes, the edge does get blunt. And you can notice it in close up photos. However, does it get blunt enough to affect performance? After all, it's not like a knife trying to cut through a piece of meat

It doesn't just affect performance, blunt edges make skiing down icy patches impossible. The effect is so pronounced that if you do enough skiing in a day you'll notice a difference even at the end of that day.

The effect of a newly sharpened ski is noticeable immediately even if you're an absolute beginner. Even moreso if you're on a snowboard.

Try taking a slice out of a block of ice with a butter knife. Try again with a sharp butchers blade. The difference is quite pronounced.

The question is whether this is a good model for an actual ski on ice. What you describe might be a good model for an absolutely perfect carve, but that basically never happens in reality. When it does, it’s on softer snow where the tuned corner of the edge is a negligible part of the overall interaction with the snow.

I agree with the quoted skier in the post, tuning skis doesn’t matter. I am someone who puts 400+ days on one pair of skis before replacing them, I ski pretty rough terrain and hit my share of rocks, I’ve gotten maybe 3 ski tuneups in my life, I couldn’t tell the difference after any of them. The only things I did to care for them was to store them dry and wax them once per season.

I have to wonder...

The article shows edges and the effect of sharpening.

However, I would imagine corrosion makes much of the surface of the ski more abrasive and that could explain the grabbiness.

Is there any science behind the edge assertions? almost all of it is anecdotal.

I can't help but think of overengineering and a/v systems.

For example, I can't tell any difference from different speaker wires (except bad cables), but I do notice hiss in amplifiers. And I think OLED might be superior, but honestly dark scenes are horrible during daylight hours unless you have blackout curtains in the room with the panel. No review or marketing ever talks about these practical details. Same with reflections with glossy screens.

Other people are reporting that they can feel it with ice. Do you ski much on ice?

You can see in this video that the interaction of the ski with the snow is much more than just the edge of the ski. I really doubt the fine tuning of the edge matters that much.

I don’t think there is any objective way to settle this debate. I think if you enjoy tuning skis, go for it. I like sharpening knives and tools so I get it. But I don’t bother with my skis.

I'm not the submitter, but I'm guessing that they thought it was interesting and thought others may also find it interesting. And so it proved.

And as it is completely in keeping with the guidelines, it hasn't been removed by mods either.

That'll likely be why.

0.5 for base bevel with three degrees for the side is very aggressive for his age but his cuff alignment is dialed and he can handle it.
