I have a lot of old tools I regularly use (old tools from my dad).
I have a set of Britool torque wrenches:

I also have the middle one (not shown)
These are my only torque wrenches in the normal ranges (below 250Nm). Taking into account how much I mod my car, these are used almost on a daily basis and I love them.
Yes they're heavy, dont have a ratchet etc, but they are so durable and have an immensely positive click. They're I think over 50 years old now, and still accurate.
And the best thing is, they also work anti clockwise, which is a very very important feature if you do real spannering. There are quite a few bolts inside the engine which are right hand thread and need to be torqued down.
I also use loads of old pullers etc. Back in the day when my dad bought a lot of tools (60's and 70's) you could only get premium brands so lots of that stuff he bought back then held up pretty nice (and he was very sloppy with his tools).
Old Kukko hub puller:
This puller is still made but I'm now way to cheap to pay €250,- for a hub puller (thats how much they cost nowadays

), so when I need something I usually buy the cheap chinese stuff. If that breaks too soon, only then I buy quality german tools, and probably used first if I can find it. Used you can sometimes find real steals. I needed a big torque wrench, so I bought a 760Nm dremometer (all aluminium) for €35 used:

These still retail for €800+ new!
And of course lots of 40-50 year old gedore/hazet wrenches that see regular use. You can never have too many tools
oh wait, this is all not conform the TS.
Oldest tools I bought new and are still in use are I guess from the mid-late 80's
These 2 sets of watchmakers tools (wrench&nutdrivers) I still use for small stuff, and I have them pretty much as long as I remember. These are from the mid 80's I think, as I bought them when I started to race with model rc cars.

Weakest point is definately the plastic boxes they come in. But they see lots of use as I'm also always tinkering with small stuff.
I also have a small row of tengtools sockets from the mid-late 80's, I think in BA sizes. Not that sockets of that age are special, but tengtools had just started out in those years. I dont know if they even have the same logo
