Kind of like the difference between right and left handed pliers?
I was tuning my VW one day and using this wrench to turn the engine over. Dad comes out, and being a smartie, asks if it's a metric wrench. I give him that eat it look, then glance at the wrench and see the 200mm on it. So, I said why yes, as a matter of fact it IS a metric crescent wrench & showed him. Dont think he'd noticed that before either.
Fun times.
