The elbow guard u can make out of sintra plastic or modify a sports elbow or knee guard, and attach the blunt spikes (I made those out of wood)
Heeeey. Great idea! That might come in handy for other Cosplay-things!
My Aeris bracelets are made out of wood (coated with primer, and painted gold). Unfortunately, my father made them for me, and I had no part in it-- I can't very well explain how he made them! However, if you know someone who works with wood, they might be able to make you a pair....
Okay, I was bored, so I made a drawing of what my cuffs are like! Maybe it will be able to give an idea about how to make some.... See attachment.
