I used to be really neurotic about tuning. I'd touch up the side edges with diamond stones and wax every 2-3 days or so. I have a whole toolbag filled with ski tuning tools, sharpeners, edge guides, base planes, wax, a couple of ski irons and then some. Now, I don't really do it often. I keep the edges of my race skis clean and sharp by not skiing off-piste. I waxed them maybe 3x and haven't touched the edges in a year since I got them...probably around 20 days on them. They will still cut your finger. My daily drivers look like hell, but hey, that's what they're for especially with the terrain I ski, I can't complain. More importantly, I still get as much or more enjoyment skiing now as I did when my skis were perfect all the time. I haven't brought a pair of skis in for any professional work in 10 years. Now, I save the money and keep my eyes out for good deals in the off-season and buy new skis and do whatever works needs to be done myself. I still like to work on my skis when I have the time but as long as I have one pair of skis with edges, I'm good to go.
