Hockey players aren't trying to land with heavy impact on the blade. I completely understand why we don't have a quick-release system yet - it would be patently dangerous if done wrong!
And hockey players end up losing blades during the game sometimes and then have to basically crawl back to the bench. It can actually get pretty hilarious since they normally aren't hurt or anything. For example: https://www.youtube.com/watch?v=WB5b3xiTW4c
