I obsess over my tunes and pay a lot of attention to my skis after a session.
Something I have notice recently it a well tuned edge develops a hanging burr after a good carving session on icy snow.
From the mechanics of the interaction between ski and snow, I would expect the burr to be pushed out laterally caused by the sliding motion of the edge across the snow.
But no, the burr is pushed out vertically leading to a slight hanging burr that I can catch my fingernail on.
A couple of passes with a fine stone in a base guide removes the burr but I cannot see why it forms.
The hanging burr seems more pronounced in the forebody of the ski.
I'm an engineer and it bugs me that I don't understand the dynamics of how this happens.
Does anybody have a clue?
