My girlfriend's dad has a huge portable Craftsman tool box that is full to the top with sockets like that and he just pulls that out when he works on something and fishes around grabbing ones that look around the right size and sticking them on until it fits the fastener. He's been a mechanic for 25 years though so I guess it works.
When I bought my 1960 Craftsman box at the estate sale in 2002, the lower drawers (a deep one) was packed with combination wrenches of every kind. Actually, when I came upon them in the garage for the first time, they (the seller and his son) were in the process of organizing the wrenches into Castrol oil boxes to make sense of them (which they did very well).
The box belonged to the man's FIL (the kids's grandfather). I made sure after I cleaned it up and won a contest with Sears that I go back and show them what I'd done to it. The man said, "Look at Poppy's toolbox all cleaned up!"
