Hello Hawker-Blue,
thanks for asking prior to the convention. :3
Due to the theme this year the weapon policy is a tad less strict than usual. Unfortunately it isn't really possible to say what is acceptable and what isn't as you would be astonished by the things people come up with. And yes, "peace bound" means, that the sword is fixed in its sheath/holster by a cabletie, a piece of string or the like.
Now to your sword: If I got you right, it is made of wood and only painted. So it would be okay for you to carry it as part of your costume. We'd refrain from requiring it to be peace-bound, if you give me your word, that you won't wave it around in public or do any other stupid things that could harm anyone or anything. I still believe in common sense.
You can draw it for a photoshoot or the like, as long as you don't wave it around. Of course you're also responsible that no one else draws the sword from you to play around with it.
So, go ahead, I trust that you'll use common sense. Please honour this trust by being careful. :3
One requirement though: Please make sure that you check in your sword and every weapon that you might have with you in the ConOps office as soon as you arrive on site! If you're encountered with an unchecked weapon, we'd have a serious talk. ;3
