While not a socket, Elroy offers this
"Bitch Hard" Early Indestro Nut and Tap Wrench from the the 1920's
You may wonder: What exactly is
Bitch Hard ??
When Elroy first took possession of this antique, there were a few burs left over from the stamping process. I heard Elroy state in amazement, Son of Bitch that thing is HARD when the file slid off without so much as leaving a mark.
You can see the heat treat colors are still clearly present
The 1" opening on this old soldier performs well on fuel fittings that call for a thin open end. I've watched Elroy use it on several occasions
