"And increasingly specific screwdriver sets supporting obscure screw types that no normal person would be aware of."
Which are needed when someone presents you with a repairable thing that has such screw heads.
It is known that I went to a UK Secondary Technical School (12-18) and worked in IT. It follows that I am assumed to have all necessary wood/metal working, plumbing, electrical/electronic, and IT skills (and materials). As well as more academic areas backed by my 2000 book library. If neighbours' kids have a school project then my door bell rings - usually the day before their submission deadline.
The only thing I haven't been able to provide for a neighbour is a bolt cutter - when one had lost her bicycle lock key. I am sure I saw bolt cutters in Aldi once - must have been in a hurry that day.
A neighbour recently asked** me to renovate her garden seat. Unfortunately the nuts on the slat bolts were rusted in place - and no room to get a hacksaw blade in. Hey presto! - the nut splitters bought in 1972 for a task on my 1956 86" LandRover.
**The neighbours ask to borrow a tool - and it soon becomes obvious they have no idea how to do the job. Usually they send a kid to ask for "a screwdriver" or "a spanner" with no indication of what variety. Renovating the bench started as a request to borrow "a saw". Eventually the job required two types of saw, the nut-splitter, electric plane, electric sander, wood chisels, screwdrivers, rule, tri-square, and digital caliper. The latter was an impulse buy from Aldi and has proved invaluable on many occasions.
