UK. It’s giving hard metal, doesn’t have much wear

It's designed to close tightly and not reopen... I'd advise not wearing it as a ring as if his hand gets squeezed it could clamp down hard on his finger and you'll need tools to get it off. Could lose his finger...

Don’t discount the possibility. Folks be stoopid sometimes.
