So, I've graduated from "marching" to beginner forward stroking, and I've noticed that my right blade makes a lot more noise on the ice than the left blade does. The left one is a very quiet hiss, while the right one is more of a scraping sound. What could this mean? Are my blades sharpened unevenly, or should I look for blade damage, or is it just likely that I'm dragging that foot on a bit of a diagonal instead of gliding straight? (My right side is definitely weaker than my left.) Do I need to adjust the blade mounting on that side? Or is this just normal and nothing to be concerned about?
