Any topic that involves gear tends to focus way too much on stuff you can buy rather than the skill. Get tools that don't break and learn how to use them. Off the top of my head the only hand tools I stick to high end brands for are screwdrivers and slip joint pliers. Too easy for cheap ones to round off or break your fingers.
Yeah, I would also add axes, knives and saws to the list.
Recently it was necessary to disassemble the knife with torx 2 screws, it is very difficult to find suitable bits or screwdrivers here. There are almost no quality ones on the secondary market, since these types of screws have appeared quite recently. It was possible to buy high-quality Wiha at the primary one, but waiting 1.5 months by mail was too long and too expensive for a one-time job. I bought a set of bahсo. The hardened screws broke the ribs on the screwdriver 4 times, I had to grind the damaged part with a grindstone manually. This process took about an hour. If it was not a hobby, but a job to order, I would not have been invited a second time))
The knipex has very useful pliers with parallel jaws (pictured above), they always squeeze the nut without licking off the edges. My plumber friend paid for them a long time ago, he is engaged in plumbing and sewerage for wealthy clients. They really don't like it when their shiny tub nuts scratch during installation. This also applies to cheap equipment. The bolts are sometimes practically not hardened, and when you unscrew / tighten often for repairs and the edges are licked off with ordinary keys, this causes a loss of time. If the bolts have become completely unusable, then toothed pliers help (pictured below), their teeth are hardened and bite into the metal, everything is easily unscrewed
About cheap axes - ax that dulls worse than bronze, that is, becomes dull after every couple of blows, this is annoying. I recently dug it (on photo) out of the ground while raising the foundation of a friend's house. The ax has been lying at a depth of 1.5 meters since the construction of the house ~ in 1950. The high-carbon steel blade is welded onto a soft base at the butt. After sandblasting and sharpening, it works at the level of very expensive modern axes. Mainly because at that time, if you make bad products / defects in a state-owned enterprise, then you are very likely to go to jail
Oh, 1 more very useful thing, saved my toes many times - boots with an iron protective cap. First of all, you need to choose them so that they are comfortable for the foot, especially if you have flat feet like me, so that you can move for a long time without pain. And a steel protective toe. They are not very expensive actually. It's about $25-50 here. Service time is about 3 years. After three years, the seams begin to rot, for no reason, it just takes about 3 years and they fall apart. Planned obsolescence((
Very good - Italian company Cofra, but they are more expensive - ~$100 and more
Well, skills are the main thing, if you give a fool a good tool, then this will not help him)) It is better to model all the stages of work in your head or even paint them on paper. This takes some time, but can be useful later, something like making a shopping list in a store.
