This is a claw hook used in the James Cameron sci-fi film Terminator 2: Judgement Day. When the T-800 (Arnold Schwarzenegger) gets out of the police car and shoots the T-1000's (Robert Patrick) left claw, he falls off of the car, but part of the claw is still left in the trunk of the car. John Connor (Edward Furlong) then throws it onto the street, and we see it bouncing repeatedly, reaching T-1000's feet.
This T-1000 claw hook is made of very dense rubber, electro-plated in silver chrome and is in good shape with some minor surface wear and a few imperfections which is common on this stunt piece.
It's presented in a nice custom made acrilyc display featuring the movie poster and a couple movie stills. The custom display case measures 15" wide x 12" tall x 6.5" deep.
