After tuning my skis, the side edge looked like it was "stepped". It looked something like this cross-section:
---------------------- Topsheet | | \ <--sidewall \_ | _| <--edge _____________________|__| ^ ptex edge's second bevel
I ended up taking back the side edge to remove that second bevel. However, I'm really confused about how this could happen. It wasn't just dulled, but rather like a cut-out had been made the entire length of the ski about the thickness of a fingernail (so just a tiny sliver)... it also appeared to only be on one edge of one ski. Any thoughts on what I might have done to cause this?
