I'm thinking of maybe a Tanto for Zircon and Azurite? Short, straight-bladed, single-edged japanese sword? The shortness and the straight blade coming from the Katar and the single-edged and japanese origin from Zircon? *Shrug*
Well I thought the chakram could be the handle and then the blades would be Zircons Katana. I figured maybe the scissors could come apart to make two blades if they wanted too
That list helped me so much when it came to making Megucas. Fun fact: Microcline was originally a Meguca and Evenkite was meant to be a gemified version of one of my Megucas but turned out utterly different and is now her own character. Also, said Meguca was a boy. Meaning once upon a time, Eve was meant to be a dude. And if you don't know what I mean by 'Meguca' I highly recommend you watch Meduka Meguca, otherwise known as the 'what even is this' parody of Madoka Magica.
I would say spoilers to those who haven't seen the actual anime, but honestly Meduka Meguca is so utterly vague, bastardised, and stupidly funny that I'm not sure that warning is warranted. XD
