Making a daredevil billy club need some help?

hey nice idea and pictures you found there......for the grappling hook i would find something with a similar mechanism.....you can find these in many childrens toys.....after you have found the right one.....find a way to adapt it to your cane................as for the rectactable wire...........i would abandon the wire idea as it is too hard to adapt and maintain.........however you CAN adapt this into your cane http://www.eabookstore.com/bookstore/images/Lanyards/ID14.jpg just strip down what you can and place it in your cane......use lots of hot glue to hold it in place i too have bee ntrying to make one of these.........but i always end up getting sidetracked by wolverine claws....punisher,deadpool iron man or war machine..........good luck hope it helps
