I don't care buy tools with the vice grip name on them any more. They are the people who wiped out the entire village of De Witt NE by moving the plant to China. http://www.livinghistoryfarm.org/farminginthe40s/machines_12.html I have quite a few adjustable open ends that are metric size, that is in length, because I brought them along from Europe. As far as left handed, they make them with left handed threads on the adjustment. I was born left handed, but was forced to write right handed in school. I use both hands. The left handed adjustment seems more natural when I have the tool in my left hand.
