There is a little bit of a survivorship bias with regards to old tools. The crappy ones broke long ago but the quality ones survived. But also, there were not the modern manufacturing methods we have now back there. There was no hammer with a plastic integral handle, everything was wooden and cast iron or tool steel. You could easily buy or make a wooden replacement handle when the old one rotted away. There was no dirt cheap Chinese forged metals so everything was more expensive and you took better care of the metal parts. Dulled edges were sharpened, peened hammers would get grinded down, broken rivets could be replaced. The few electric tools were beefy, simple, and offered easy replacement of the brushes. You also may have just experienced what happens when poor people have little access to the latest and greatest cheap stuff at the store, they make do with what they have. Compare that to the numerous old cars still on the road in Cuba, parts are difficult to source so when something breaks you'd go to the mechanic with a rudimentary machine shop that could fabricate a replacement part.

We still have quite a few tools from the early 1900s at home. Scissors, a hammer, an old meat grinder. Everything made of iron, heavy as hell, but nigh indestructible.
