OK, if we're going back to childhood cardboard days, I made a Freddy glove from cereal boxes. Later I upgraded to strips of metal snipped from Coke cans. I was in maybe 5th grade? Funny how some people just get that little itch to MAKE something...!
My father build me my first Raphael Sai from turtles, I also got a Leonardo ninja sword and a hoverboard made from wood, and painted...
Similar to mine no pics still exist but my first prop was a Mikey Nunchuck made from a piece of wood, some chain, 2 screws and foam pipe protector covered in electrical tape.
It only sorta worked.
