I was brewing a few weeks ago when a carboy slipped about 1" off the floor and cracked in my arms. Cut my wrist open and severed my ulnar nerve and tendons. I had surgery to join everything together, they had to open my whole arm up to round up the tendons and move my ulnar nerve to inside my elbow for more slack. $15K was the bill but luckily my healthcare covered it. I have no use of my right pinky and ive been in constant pain and nerve damage numbness since. 1 year recovery the doc says, chances are i should make a full motion and strength recovery but have sensation issues for the next few years.
Moral of the story, don't be cheap or lazy. Make wood crates or buy carry slings for all your carboys. Or even better ferment in buckets, kegs, or anything but glass. Im not here to convince everyone to boycott carboys, just realize the dangers of moving a potential butchers knife around your house. I'm making the move to sanke keg fermenters using CO2 to push the beer around.
