I used to make fire swords as one big piece of metal covered in material which was then covered by wire. This instructable shows you how to go about it so that the flame illuminates your actual sword. For this instructable, I used machetes you can get at Harbor Freight for about $5.00. All in all, you'll need 4 machetes, a hand drill, a 1/4 inch COBALT drill bit - most other types won't work, and they didn't have titanium bits in that size, A DRILL PRESS AND LOTS OF PATIENCE, a dremel with a cutting wheel attachment. welding blanket, and some nuts and bolts for each hole you make on your fire swords.
but i love the way you did this its so simply i would do it with only 3 though
All in all, fire swords are awesome and epic, and fire swords which are easy to make are much more so.
5 stars, purely for originality, bonus star for it actually, logically working.
