Is it necessary to remove the lip with an eraser after using the Roto Finish for sharpening the edges of skis or snowboards?

It is always a shame to use an abrasive gum that slightly rounds the edge when it is well sharpened.

The ideal is to grind the edge slightly with the long diamond file 400 in the file guide to fall 0.5 ° or 1 ° before sharpening the side edge with Tuning File or Roto finish but very lightly (one to two passages with a very light pressure).
