Interesting & creative tools, even if they are flops

Curiosities that are obvious what they do, so don't go in the "What's this tool?" thread.
Whether they were successful may be another matter - but someone(s) thought they were worth making. :)

No name, Made in USA, Nut driver with built in storage on the shank. LOL Handy or annoying ?

I have one. Somewhere. It came in Sears largest tool set around 1970. Useful? Very little. Used it a few times over the years just not real handy as jaws are spring loaded so ot doesn't stay tight. Regular nut driver better. So is Speed Handle, which I have always used a lot.
