I have an aluminum-bodied Craftsman circular saw that is my go-to saw. With a modern thin-kerf blade, it cuts beautifully.
My Skil 77 worm-drive circular saw is at least 20 years old, and more likely 25 or 30. I have a pallet-cutting blade on it and use it for demo and rough cutting jobs. It took down an entire carport made of rotted, nail-impregnated wood a few years back. It sliced through nails, sheathing, shingles, and whatever else was in front of it. I changed the oil once when I bought it, but that's about it.
My Milwaukee Sawzall is also a cast-aluminum model, the only sawzall I have. Single speed and weighs a ton, but it'll probably survive doomsday. Probably due for a restoration soon.
I have an aluminum-bodied, corded Black and Decker screw gun, the type used for hanging sheetrock all day long. The cord is rotted out and it needs to be taken apart and lubed, but it drove a LOT of drywall screws in its day. If cordless drivers weren't so good, I'd still be using it.
I don't know if 20 years old counts as vintage, but my corded Makita 1/2" VSR drill is at least that old. Loud, heavy, and a real arm-breaker. I've run it wide-open drilling concrete with carbide bits masonry bits before I had a hammer drill and it just flat-out works. When I need a real mother of a drill, that's what I reach for.
I recently donated a working Skil 3/8" corded drill that had to be at least 30 years old. It was plastic-bodied and beat up, but it worked flawlessly and had some serious torque for a 3/8". Someone will give it a good home, I hope (probably some idiot like me who can't resist finding a home for every stray tool he sees).
