But it makes me wonder how many of us have had tools for years (decades, even) that we haven't touched and yet still refuse to pitch? I have a bunch of Flathead V8 specialty tools from my Hot Rod days; Valve spring tools to get the keepers on, corkscrew wires for replacing the mainseals, etc. I still have a Sears Dwell/Tach that only goes down to 6 cylinders 
and a bunch of tools for snowmobiles, but I still use the very same soldering gun I used to build my first Ham Radio transmitter back in 1960. It's got a lot of electrical tape holding it together, but it reliably works.
I refuse to give up the 10" Skillsaw that I keep up on top of my shop cabinets, though. At about 15 pounds, it feels like you're hefting a small car but it built my Dad's house and still runs. I have, and use very often, his carpenter's hammer, too. That's not going anywhere, either.
