Before the knee went 'kablooey', I had my blades sharpened by a highly recommended sharpener. When I skated in them it sounded like a tiny, little chain saw.
|I am badly sharpened skate, hear me scrape|
So, I posted the problem on www.skatingforums.com and one of the coaches there suggested that my edges weren't even. That is, even when I was supposedly on the flat, one edge was slightly higher off the ice, leading to the scraping sound. When I was on an edge, the side with the edge that was slightly longer, could brush against the ice, causing scraping.
|You can see the edges here, they're supposed to be even|
I guess I'll query the Amazing Coach and find out what her 40 years skating experience says. It's an interesting technical problem. There has to be some vibration in the blade somewhere, because you can hear it all across the rink. Over.The.Music!
|Everyone hears my blades....the shame, the shame.|
