My girls both coach and ski race for their high school.  I’ve always maintained their edges since our snow tends to be icy often, and I’m an aerospace engineer and metal worker by trade.  This is probably the best video I’ve seen on this.  Watched this as a refresher.  Thank you.

What is missing from most (all) videos is "how it should feel" when filing an edge (bumpy, biting, smooth, etc). Thanks for pointing it out. Really helpful.

I appreciate the bevel guidance at the end of this video. Remarkable how many people neglect that discussion in their how-tos!

great video. the best information I have seen in any video ever. but, buy a microphone

Haven't tuned my own ski's in 15 years. Life got in the way. Getting back into it. I thought your video was very good. Just read all the comments and looks like the world agree's ! Phew.. I'm supa smaht again !!

Great video！

10:48 Detune tips and tails

Very detailed video. Congratulations. If someone gains even a little experience, they can really tuning or repair skis on their own. Of course, the tools are expensive and to buy everything you need, someone has to pay at least 300 euros.

one of the better ski tune videos on youtube😊 thankyou

Personally, as someone skiing on wc skis I always like detuned tips and tails. If the tips and tails are too sharp in my experience, the skis can hook too much and be really tough to transition out of a turn. I would say always keep a gummy stone in your bag and detune when necessary

Thank you! I realy like the theoretical models/scetches as intermezzo's in the video. Especially the fact that the a). base and b). side edges add up for the edge cut!! Finally understand edge tuning after watchting this. Thnx.

snowboarding, love my gummi stones for tuning and deburring on the mtn. gummi stones dont take off as much as a diamond file and easily removes rust.

Thanks for putting this video together! Im a mechanical engineer, so not a materials expert, but I dabble. In the video you said that when you hit a rock it creates heat, and that hardens the edge. I believe that when you hit a rock, it "cold works" (or strain hardens) the steel edge, which means that by deforming it, it disrupts the crystal structure which makes it more stiff. This is because the defects in the crystal structure make it more difficult for the crystal planes flex and slip past each other, so it takes more force to deform (or in this case cut) the metal.

Thanks for answering the panzer vs. chrome file conundrum that noone seemed to be able to answer.

Yea, thanks Jon. I watched a few and yours will be saved and serve as my reference. Next, it's off to the hardware store :)

Great tutorial.

Very descriptive and thorough . Thanks !

Excellent guide!

Awesome vid!  Very informative.  Thank you!

Wow! What a lesson!
