This guy spent a lot of time and finally made a real Batman grappling hook. This admirable rappelling/grappling gadget is a nice piece of engineering. The Hacksmith’s upper-body and arm strength is also very impressive. He can make good money if he starts selling his self-made batman grappling hook or set up a kickstarter to make more of these. After this, he should start working on Spider-Man web slinger project and make a cool spider-man video.
