Normally I am very careful with my skates but today I was leaning out the door where the matting ends and the hard floor begins, lost my balance, and touched my right skate to the hard tiled floor. Thought it'd be okay since I barely touched down, so went on the ice and it was definitely dull, so dull that even putting my weight on the edge would cause it to slide right out from underneath me. So took the skates to the pro-shop and asked the guy there to fix my edge, and he sharpened it then showed me that the edges were level with one of his tools. So very thankful that somebody was there who could fix it, as half the time there's just a hockey kid there, otherwise I woulda lost out on 1.75 hours ice time.
Moral of the story: Never let your skates get within ten feet of a hard surface. Something will happen.
