It doesn’t appear to be terribly bright either. And obviously that’s not the sound from it.
I am curious to see it up close though, could lead to all sorts of things for us.
I dunno, the more I'm looking into it, the more it looks like a gimmick to get the attention of the muggles. It looks cool, but apart from that, I'm just seeing drawbacks everywhere. You need a huge hilt, the blades are dim and don't look like they'd hold up to any impacts, very little real estate on the inside for anything else.
I would be curious to see one taken apart, just to see if there's any improvements that we can come up with, but I'm not exactly holding my breath.
