1/8 inch drive

There is a series of 4 sockets and a handle. It is like a dental tool and I have not found a real use for it

The 1/8 inch square drive is here because it is pretty cool. This set appeared and then disapeared. I can guess why - it is too small.

The 1/8 inch square drive had appeared by 1970 in consisted of only 5 parts. This is a very small set (in numbers and size) this will easily fit in the palm on your hand. There is a small box  and one option in 1970, a bit holder.
