Two suggestions:
1) 711 EDC ratchet https://www.amazon.com/gp/product/B09MJYRQP4/ (this thing's a godsend)

2) Galvanox 1/4 bit extender: https://www.amazon.com/gp/product/B0BMNN8JB3/ Way cheaper than Leatherman's and has mostly good reviews. Seems to have some QA issues here and there, but seller seems pretty responsive to issues & does fast replacements. Would add a 6x2mm magnet if needed.
