If the edge is blunt, you can count on the fact that the first icy plate will not only surprise you, but also your colleagues around you in terms of your comical performance to save you from falling. If the edge is rusty, it will probably take a while before the “bloody” rust track disappears in the track behind you and the sliding speed returns to normal. The sliding property of the base surface depends on the possible sticky snow (probably fresh snow has fallen and you forgot to lubricate again, or the snow temperature is higher than 0 ° C and you are standing, because your skis simply do not move – so called mirror effect, when water stays between the two surfaces and does not go out)… Anyway, service should not be performed sporadically, only in a crisis situation, but regularly. Regular service is a prerequisite for better skiing experiences, sports performance, but also safety. Structuring the base surface, including edge angling and wax impregnation, is usually carried out several times during the winter season, taking into account the frequency of skiing and the snow conditions of the area (stones on the slope, natural snow, technical snow). It is essential for the skis or snowboard to be prepared before the start of the season. In this respect, we recommend to have extensive service at the end of the season so that the impregnating wax layer on the base surface is not fully removed, on the contrary, it is left due to the summer preservation of the area and the lower edge – we recommend final polishing of the wax only before the first skiing. For many of you, it will surely be surprising that even new skis need service. As an example, we can mention a racing ski program, where 90 percent of competitors have the manufactured “semi-finished” skis and boards re-formatted (surface and bottom edge alignment, final structure, side edge angling, bottom edge tuning, impregnation) ”.
