This little puzzle has been a mainstay for years. Sold separately, as this one is, or in a set of several puzzles. A starter puzzle, if there ever was one. It has been made by many manufacturers, of varying quality, and given several names; a common one being “claws”.
This particular one is made of heavy steel and will not be bent or broken without using major force. It won’t take anyone long to solve it; even blindfolded.
