I recently bought an antique chair, literally from the 1800s. It is a little thing, probably a child's chair. One of the legs broke. At first I was sad since it was a nice buy ($15?) and fit exactly into a little space I had for it. I mean, it survives a hundred years and then gets broken by my idiocy within weeks? Then I had a look. The thing is put together with no screws. It's literally a friction fit for every one of the 4 legs and cross braces. So fixing it is as easy as spinning up a wood lathe and making a new leg. And it turns out...it has been repaired already. This is why it has lasted 100 years.
