I sure dont. But thats true of most things I look at. I just start trying tools till either something fits or I resort to a crescent.. Id bet on it being metric, of course,,
Blows me away when I get into a job that has them mixed, an SAE here, a metric there, pretty soon I cant even guess what Im looking at.

Pleeeeeeeeze, no fitzsalls !!

To me the difference tween a good bike and an emaculate bike, could be if it was fitzsalled or not !
