I have a bunch of tools from my grandfathers… one was a millwright, the other was a German machinist, millwright, and mechanic that owned his own service station in the 50s and 60s.
When I reach into my grandpa’s toolbox looking for some oddball tool it’s amazing how my hand often graviton the exact tool I need.
On the tool pron side of things, this is something I got recently and it actually incredibly useful.
Cordless soldering iron.
