What do you think about rounding off your new skis sharp edges? Do you guys do it?

Same I would just ride till they dull. I was thinking get a metal pipe(similar to a rail) and start rubbing. Or a grinder of some sort.

This is what I do. Just rub it underfoot a couple of times, then swipe a gummy stone over it to de-burr it.

i do it on my park skis but i would not recommend it for non-park skis.  I generally do it from a few inches in front of my toe piece to a few inches behind the heel piece.  i use a file and if there isnt one around ill use a rock and if there isnt one of those then i just slide my edges against each other.  It doesnt have to be a super aggressive de-tuning just enough to round the edge enough that it isnt catchy, then repetitive use will do the rest.

I detune every pair of skis I own in some way (except race skis...but I don't own any of those anymore).

Park skis - light detune, tip to tail with gummy stone, heavy detune underfoot (light filing, heavy gummy stoning - or belt sander if I'm able to detune at work).

All-mountain skis - super light detune tip and tail (sharpen underfoot - 89*) to prevent hooking (maybe one or two passes with a gummy stone at moderate pressure)

Powder skis - moderate detune of tip and tail (sharpen underfoot - 90*), especially if rockered (gummy stone only, a few more passes than all-mountain)

Detuning can prolong edge life and prevent catching and hooking (both on rails/boxes and snow), it's worth the effort as long as you don't go overboard you're good.

I do the worst thing possible for my park skis, take the Makita with the flap wheel, make sure the direction of rotation is shooting sparks away from the base, and start doing nice, light, and long passes at about a 45 until I have a nice bevel from a few inches in front and behind the bindings. Then a quick clean with the gummy stone.

take a gummy stone to just under the foot some. i wouldnt recommend dulling them down entirely. remember to detune the tips and tails as well.

You can just put a 3 or 4 degree base bevel on them, then you still have sharp edges and you won't catch or damage anything

I don't for brand new skis. I use my new skis for carving and free skiing. When those get old I take them to the park. But you can pretty much just take low grit sandpaper or an old side filer belt and take that to your edges. You can probably see if your local shop can let you use a little piece of an old belt.
