Easily to say the least, I'll do it like a recipe, I was once a chef. ingredients: 1 metal tube (Like a chrome pipe) 2 D batteries* 1 roll of brass or silver wire 4 led lights 1 small cardboard card 2 brass fasteners 1.paperclips some plastic or anything that can shape the blade intructions: 1. First check the supplies to ensure that they are all usable and still working 2.Rig up the wires to the batteries with a long line of wire all connecting to a led light, then make a switch by putting both brass fasteners onto the card and a paperclip conecting the two tops, on the bottom, make a gap in the middle of the circuit and rig the switch on. 3.Put the battery part inside the tube and saw part to make the switch stich out. 4. Insert the led lights into soem plastic or something like that to make the blade 5.attach the blade to the tube 6.Use any other materials to customize it to make it your own. Tips:You can use rubber rings to make a grip and a metal ring to put on it. *Depending on the brightness you want the saber to be or how long the tube is, you can add or decrease batteries.
