Here is a man wearing a hooked metal thingy attached to his belt. It has teeth that look like they're meant for grabbing hold of other objects, possibly heavy ones. Maybe he uses it as a makeshift hand tool when necessary. I wonder what it's called. The metal device seems sturdy enough, and the chain connecting it to his pants looks quite thick too. It almost appears to be some sort of tool used by craftsmen or laborers in industrial settings. What's its purpose, do you think?
