Funny story. One of mine broke a long while back, foolish me is like oh, I can fix that. Go to HD and buy two new ones, figure ill replace both.
Get out the ladder and a big ass socket wrench and go about loosing the non broken one. Just about the time I think to myself “seems like there is some tension here” the thing breaks loose. Socket wrench snaps around in my hand the socket itself hits me square in the sternum and off the ladder.
Holy hell that hurt, time to call the professional. Guy comes out and takes a look, says “who loosened that?”
“I did”
“You still got all your fingers?” (Which is funny now because at the time I did)
“Yeah” and I lift up my shirt and show him this massive 3/4” bruise on my chest.
Dude about peed himself laughing at me.
Lesson learned. Somethings you call the pros for.
