I came across https://silverfoxtools.co.uk/ on a recent visit to kickstarter and have backed their Atom Wrench... I think it will be great alongside my pocket driver.
It has a similar style to Metmo products even if it is not quite as satisfying to use as the driver or grip.
I saw this at the time. My problem with it was it was I'm not convinced the jaws are as stable as the grip. I'd love to know if I'm wrong, after it's been used a for a few months.
Very cool find! Thanks for sharing!
