1 piece of heat-shrink tubing to insulate your solder connection between EL wire and stereo wire (RadioShack) 1/2 6x32 clear polycarbonate screw to hold end bushing in (this is a recent addition, because the end bushings have come out of some of my blades when they are dueled with. However, these are rather expensive, as screws go. I think I payed about $10 for 50 screws.) hot glue, or silicone for end of blade super glue to glue in top and bottom bushings Note: I don't really like RadioShack all that much. I have a much better electronics store locally that I use that has a better selection and cheaper prices, but you can't order from them online, so I know you should be able to find what you need at RadioShack) That's just for the blade.
