Former junior and Masters racer here. Glad to see there's some very qualified voices in these comments, including a few who are currently involved (as racing parents). I very much appreciate the level of technical detail and accuracy in those comments. I'll talk base bevels all day. Pretty much agree with everything those folks have written. Most definitely sharp edges, and your bevels, matter when you are really pus…
Rocks are mostly an off-piste issue, but I have seen it happen on piste. Especially early and last season when cover can be low. Will occasionally also happen near the lift when a spot gets warn low. When I get rock gashes, it's always easier to just send them to the shop's machine.
Handling also introduces a fair amount of nicks. In theory, the edges should never meet at an awkward angle, but it happens. Skis slide around on the rack, skis flip out a position while carrying them, things shift in the car, etc, etc.
