This is the Energy Sword that my little brother came up with.
About this creation
After being let down with the energy swords that are out there, my little brother made this one out of a lego pipe and bionicle eyes. I suggest that you adopt this style of sword for yourself.
He SAYS that to keep the blades steady you just need to find the right kind of piece with the right kind of mojo. Like how some minifig hands bearly turn while others are really loose. Or you could bite the end just a tad to nip it into one of the slots.
This is fairly simple. I would like to challenge your brother to a MOC- off. I am 13 as well. I would like to see him build a stadium, and compare it to my Champions Park stadium. I will probably have it built out of actual Legos by January. I originally built it on the Lego Digital Designer (LDD). By the way, his speeder is a 5/5. I will eventually build one out of some of my spare pieces. Please check out and comment on my MOCs. Sorry this comment is so long. Side affects from reading it include the following: slight fever, hair loss, obsession with megabloks and other lego imitators, abdominal cramps, brain freeze, arachniphobia, alien abduction, strange addiction to laxatives, death, many fates worse than death, and the urge to look at my MOCs.
Oh, yes. I hadn't found any other sword like this. I've made a sword like that too. First one of that kind. So, my design is similar but i invented it myself. So I didnt copy anyone. It's a pity i havent put any pictures about my sword. But I agree this is the best sword here.
