I got a flex head 3/8 ratchet – the ‘pro’ version with a thin handle (no rubber grip etc) so easy to fit pipe over end as an extender. Flipping brilliant. I have really abused it and ti good as new.
I bought the ratchet spanners early – soon after they first came out, before flex head 🙁 Brillant but 10mm and 13mm (of course) ratchet mechanisims often lock up.
I got a 10mm and 13mm combined open ended spanner in a second hand toolshop last week. I’m so glad they exist but the chances of losing it must be double of the elusive 10 and 13 mm single spanners?
