I go to the stadium and pass them to guy who sharpens skates and say "Sharpen 'em". Shortly thereafter, he hands me back my skates and I pass him $4.
I have no clue what the measurement or dimensions or whatever you call it are. I was in grade 12 before I found out you can get different cuts, and that was only because I had them sharpened out of town and the guy doing it asked me how I wanted them done, I said sharp and he gave me a confused look.
Even after 10 years of playing hockey you learn new things.
