Just to throw in the mix, I’ve a few sets of ‘normal’ ratchet spanners, but I’ve a ramp and roller set as well.That's a pretty awesome set.
I never considered how they make those spanners but thinking about it know I might have to dissect one to find out.
Swage them shut perfectly possible, but that would bugger the chrome. But to chrome after assembly wouldn't work either.
They are mega. They work in really fine increments as there’s no ratchet mech. It’s a dowel and wedge type affair. You won’t break that! It gets tighter the more torque you put on. More likely to snap the spanner.
I don’t know why mainstream manufacturers don’t offer them more.
