^^^^^^ I cringe and my toes curl up when a self appointed "expert bicycle mechanic" decides to publish a photo, world wide, showing him/her working on a bicycle with an adjustable wrench. Oh, I forgot, metric wrenches and sockets were not invented until the '80s.
I really cringe when I witness such in real life. Adjustable wrenches are good for straightening soft steel DOs on BSOs though. Or for holding the fixed nut on a crank removal tool. Our local Giant grocery has happy photos displayed showing happy family life. One has Grandpa helping little Tommy fix his bicycle, with an adjustable wrench. Start em early, Pops!
