A set of reversible ratchet spanners. I have encountered a situation where the one way almost became trapped!
A body repair shop left a 13mm ratchet spanner in my engine bay. I still have it.

There second pic shows my motley "treat it any old how" collection. I prefer using them!

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
