> A NiCd-powered cordless drill would be my first thought, clearly obsolete since the widespread adoption of lithium battery tools and the rapid degradation in NiCd cells over time.
On the other side, as long as it's something brand-name like Bosch, these things are built to last - and there are still shops around selling new battery packs for them (or you can replace the cells yourself - no fancy BMS required like with modern lithium batteries and no risk of things exploding or going up in blazes if you mess something up!). I'm still using power tools from my grandfather, meanwhile a friend recently complained to me that one of his "new" drills broke less than two weeks in his house renovation.
The thing is, what you can buy in construction stores these days is optimized to last for the two years warranty period aka six or seven times of being used. Keep that "old" stuff, it will likely outlast you. And if you go and buy lithium-based tools, please buy brand name (=Makita) and don't buy knock-off batteries. These are fire hazards.
ETA: The worst thing you can do with NiCd packs is using them while they are nearly empty or squeezing out that last bit of power. That will drive one of the cells into reverse charge and by then it's effectively forever toast [1].
