Got this unusual screwdriver at auction today. no marking. 16 in long;7/16 dia rod; 1 3/4 dia handle.  Handle is made of some hard composition material. Handle retained by transverse rivet. Anybody know who might have made it or know anything about it ?
Just another oddity I coudn't resist.

I recognize the material, it is cloth solidified with phenolic, (bakelite) it was popular for making various things, like circuit boards at the end of the Vacuum tube era...

I have never seen a screwdriver handle made out of it tho...

I think phenolic was used as piston in disc brake calipers ,to keep from corroding.
That's an odd screw driver,I probably would have bought it also.

No names?   Just looking at the shape and size, my guess it was done by a machinist, using up some scrap material.   The plastic handle tools I have seen in ads from 1940, already had a modern look to them.   He had this big chunk, and it was a wonder material in the 1940s, chucked it in the lathe, used a blade from another screwdriver, riveted it, done.   I'd have bought it also.
