I'd almost have to believe we are talking about two different renditions of the tool. Mine is an extremely solid piece that I can't imagine breaking in use (unlike my spring compressors!). It weighs several pounds and the pivot pin is at least 3/8". I'll try to post a pic. By all means, though, use what you are comfortable with. I hate ending a "maintenance day" injured. Nearly every time it's happened, I've had a nagging feeling that I was doing something stupid.
