I have a set in the basement, a set in the garage workshop, a set in the road case and a small set in the carry bag for doing repairs at the rentals. There are duplicates across all of these sets and the set in the garage has duplicates in it and in some cases duplicates of duplicates. the duplicatescover: wrenches, sockets, cold chisels, ball pein hammers, pliers, pliers, pliers, pipe wrenches, ratchets, more ratchets, multimeters, tape measures, hacksaws, screwdrivers, paint can openers (never have too many of these), taps and dies, drills etc. I hate having to go back and forth bewteen workshops. the tool set in the garage workshop fills two 41 inch roll cabs, 41 inch top chest, a side cb and a side top cab.
