Only real guidelines I've been given so far is he doesn't want a blade, and to look at the books cover art. I did that with a Google image search, and I'm still lost. I'm thinking the top half will have a wrap in either blue or green, with a gold wire spiral, a katana like tsuba similar to one of the replica weapons I found, (the windlass heron mark sword I believe) with the emitter being a double angle style. Inner tube cut at one angle, outer in the other, to represent the claymore like part of the guard. At the activation switch, I'm thinking the heron mark on one side, the Dragon on the other, carved in. I'm thinking of either going with a d-ring belt system due to the nostalgic feel of this project, or maybe go old republic and make a sling sheath for it. Also, I've found an emblem with three rings one with what looks like blades in it sometimes with a snake I believe, (don't have it in front of me, and my heads all over the place right now) is this an emblem just for the series, or something from within the mythology?
