Once upon a time, I had a 5' pipe on the 1/2 breaker bar with just about all my 190 lbs on the end of the bar...the end of the breaker bar in the 36mm socket snapped off... ( now visualize this) I went the entire length of the shop dragging the bar, tripping over my own feet while trying to keep my balance. The shock that went though my back was unreal a couple of couch days made it better.
