My dad had a key hole saw that I used a lot as a kid 65 years ago. Hard use broke the handle and bent the blade, so the saw is long gone, and was replaced by power tools.
I should have said hard use and abuse, I was 12 at the time. I don't recollect getting in trouble over the damage, so Dad probably wasn't using the saw much, because he
wasn't opposed to warming my butt if he thought I needed it, which was often.
