I was thinking about Yankee screwdrivers not long ago, such a simple thing made more complicated by technology. Kinda want one.
Those bolt grips look like something else I need. And the palm ratchet.
In terms of low tech time saving my best investment yet was my Screwfix cheapo mattock, regular gardening tool now.
And there is nothing wrong with a quality shifter if used correctly and sensibly. Never go out on plant without my Bahco universal valve mover (shifers are banned).
