So I got bored and decided to see if I could make a prototype hidden blade from cardboard. Using a Lucky Charms box, scissors, craft knife, elastic bands and sellotape I put this together. Its definitely given me some ideas for the final one. This one is definitely too big as I can't bend my elbow or wrist when I have it on which defeats the purpose. So gonna try and make another one at some point but a little bit smaller. Obviously the final one probably wont be made out of cardboard but its given me some good ideas so now its time to expand. Quite impressed as this prototype only took me 15 mins lol.
