Whoops, don't mind the last comment about the swords. I see that you've specified them here. Okay, so if I'm dealing with semi-ethereal weapons, then I need some physical anchors. I can forge you a pair of gloves or gauntlets that will bind the phantom blades to them, allowing you to not only launch them, but to summon them and wield them like any blade at any given time. I just need to add a few runes and find these phantom blades to bind them, making them interconnect with the gloves.
