Like most on here I've got lots of spanners.
Sticking with metric sizes, I've noticed that the majority of my spanner
work is with 10mm and 13mm sizes which corresponds to M6/M8.


So what are the other ones for in spanner sets, ie., 9mm, 11mm, 12mm, 14mm
and so on. Are they just there to make the numbers up or make it harder to
find the one you want?

Certainly 100mm, 13mm, and 17mm are the most common, but other sizes
crop up. One VW I've had needed 15mm on part of the front brakes, and
they're relatively hard to come by, and not in most sets.
