Photos do not do these any justice, the edges actually glow under normal light.
I am selling mass effect omniblades made to order. I first made it for myself as a display item but alot of people were very interested in them and wanted to purchase them so now i make and sell them. They are made out of plexiglass and use velcro straps to attach to the wearers arm. I can make them for both left OR right handed use. I usually take around a week to make and have it shipped. Please feel free to contact me with any questions you might have. Thanks for looking!
Here is a video of me demonstrating it https://www.youtube.com/watch?v=SCAyl1cRoHY&feature=youtube_gdata_player
This is my version/ fan made omniblade, not associated with Bioware.
