I know nothing about Ice Hockey, but the incident in the UK has been frightening and grim. It seems odd that for all the protection the players wear, the most dangerous part of their game may be the skates they use. I know it is a freak incident, but have there been accidents involving blades before? I have never seen a skate so I don't know how sharp they are, but I don't recall incidents in other ice related sports.
