When it comes to riding the steel on skis, this is what needs to be done before one uses the skis. Do this when they are new before you ever jump on the steel. Your skis will not be grabby, and the edges will last longer.
This is terrain park ski tuning, where you don't take a file and round the edges one bit. It's a bit of work, but once you do it like this, you will never go back to rounding your edges with a file, or whatever.
