Abstract
A ski or the like has better guide properties the sharper the corner areas of the steel edge profiles. Using a laser beam, the corner areas of the steel edge profiles are hardened on the ski or the like.

Method for treating the steel edges of skis and other runner devices that have a runner base top layer with a first outer surface, two steel edge profiles mounted on two longitudinal edges of said runner base top layer, each with a second outer surface facing downwards when in use and a third outer surface facing laterally, which method includes the following steps:
- a) levelling the heights of the first and second outer surfaces if they are not level relative to each other,
- b) bringing at least the edge area in the corner between the second and third outer surfaces to the hardening temperature of the steel of the steel edge profile by laser beam,
- c) moving the laser beam and runner device relative to each other in the longitudinal direction of the steel edge profile, and
- d) drawing off heat to prevent detrimental heating up of the volume of the runner device around the steel edge profile in the area of the point of incidence of the laser beam.
