I also wanted to say some sort of specialized Blacksmith, maybe Bladesmith, tongs. Weight on the end to really help clamp down on whatever was being worked on.... But yeah, never would have guessed its intended purpose. 😮
..... Glad I didn't put my lips on them. 😁Those are blacksmith tongs. Once red hot they're used during castration of farm animals to cauterize after the snipping. Ouch!
