This is my "secondary" set of wrenches at my townhouse, not may main garage/shop. I don't do much car work at the townhouse, so inch size still dominates.
Two odd things may be apparent. One is redundant items. The main reason is there isn't a big roll-away, but a tool board & rack and several grab & go hand boxes. That's one reason there are lots of adjustable wrenches.
The second thing is sets that aren't really sets. Two reasons behind that. First, this shop was set up on the cheap, with flea market & garage sale tools. There's lots of Craftsman - all USA vintage, but Williams, Armstrong, SK, Snap-On and defunct companies like Indestro & Herbbrand, too.
Also, I like to have TWO openings of the same size for common sizes in box end & O.E. sets.
So for example, one short box set is mostly SK, but there is a 7/16" x 1/2" Snap-On, too because SK only has 3/8" x 7/16" and 1/2" x 9/16" The 15" adjustable 1mport is Sears Companion, and below it, actually not an import, is a 12" SK, both road finds! The hook spanners are Williams and Facom.
