I have a mix of types plus a “goody box” of odds and sods. The standard metric/imperial do nearly all jobs but the odds and sods are handy. I have all sorts in there including “modified” ones to fit in tight spaces, ground thinner, outer edges ground back....Stiison type wrenches, shifters, box spanners, BA sets. A range of sockets of various sizes( inherited”). They have saved me a bit over the years and don’t take up much space.
I know that if I throw some I will regret it within weeks!
