That guy reminds me of my grandfather, but that was just stupid.

I thought it was a great video.
What a waste of time. First, Craftsman is just a Sears brand name and they make NOTHING. They buy from others and to save money it has been a down hill slide for years. Second, an adjustable wrench is a very poor substitute for the correct size fixed wrench. He could have many sets of flea market fixed wrenches for what he spent on those adjustables. In his attempt to break the wrench, he slipped off several times and rounded the edge of the bar. That was caused by the inability of the adjustabe to stay tight under load. A fixed wrench would have stayed in place until it broke. I realize this was about whether it matters which way you use the adjustable but I have always consideded them a tool of last resort if I could not find the propper size wrench. He never got to the real reason why they advise you to use it in one direction. The movable jaw is strongest at it's base, close to the wrench. Applying force further out also tends to open the jaw more because of the slop caused by exerting force out on the jaw, away from the base. It is more likely to slip off. He didn't realize it but he proved my point. In the wrong direction the wrench slipped off. In the right direction, the wrench held it's grip until he exceded its strength limit and it broke.

So cute-and it can be used as a hammer! Primitive Pete's favorite.
Still work fairly well when they are used properly and there is plenty of room. As an open end wrench which is not as secure as a box end.
The weak part is the hollow in the base of the fixed jaw and the adjustment mechanism. Using it in the right direction pushes the movable jaw down against the body,giving some frictional assistance to the adjustment mechanism for holding the movable jaw in position.
The Myth lives on but a big enough pipe can bust any wrench.

And that "undamaged" wrench is sprung out of parallel.
