That's going some to break a spanner!That is exactly the sort of set I was referring to. I got mine when I was 18 (18 years ago) so it does not look like that and it is still in regular use and I have only broken one spanner and that was through mis-use, but as long as you don’t tel them that had no issue getting it swapped in store.
I have cut bits off spanners but never broken one.
