Expand-o-stick: 2006 - SolidWorks
This was an idea I had to make a fighting staff from rigid steel tape like in a tape measure. The tape can be pretty stiff if you keep it cupped, so my idea was to put notches on the edges which would interlock between 3 strips and then compress the triangulation with a net of titanium wire. The hardest part was shrinking the reels for the tape enough to fit in the end pod.
