The new shield was given to Captain by panther and made by wakanda's specialty, vibranium. Its characteristic is that it can attack the opponent like a claw, and can expand and deform. We use aluminum alloy to make shield, engineering plastic to make handle and durable rubber to make bandage. Three kinds of mechanical structures of pop-up deployment are designed and tested repeatedly to test the consistency of pop-up deployment. After many times of upgrading, we finally made the same way as the shield in the movie.There is a small pull ring at the front of the shield. Once the finger pulls the pull ring, the shield will immediately expand and deform. It's socool.
