What Is It ?

[6mm250]

Here's a riddle
I found this at the flea market several years ago.
The seller had no idea what it's for.
It appears to be drop forged steel.
It has no numbers or markings on it.
It was purpose made for something , but what ?
What is it ?

Seen something similar years ago used to screw and lift caps from underground fuel tanks.
