Anyone have any experience with this? Could I make a test model out of wood? What about if I traced one on half inch steel sheet and then used a grinder to give it shape?

How do you throw it?

I make boomerangs sometimes. Then look good but unless I use really hard wood they get messed up pretty quickly.

they sell these high grade alumanum plates down here. I was going to file down the edges and make them sharp but i have never got too that yet. Why do you need the hole in the middel? couldnt you throw it like a frisbe, like have one little section blunt to hold on to and the rest sharp? I dont see what the hole is for.

No these plates are light. The small ones are about the size of a frisbe and weigh just a little more. The big ones, the ones ment for pizzas arent that heavy at all and i hate to see one flying at me regardless of how sharp it was. 

I think that if you had a massively heavy one you could throw it like a discus and use it like a blunt force insturment.  when it hit all its energy would be transferd to the target and i think that it could cut it pretty well. Lots of energy in a big heavy plate.

grind a circlir saw blade into shape

some times they put a slick in the hole and whirled it around to get range better

Is anyone here familliar with the aerobie? If not, it is a frisbe-like toy shaped very much like a chakrum. The aerobie is the furthest-flying disk in the world. Now imagine that thing being razor-sharp steel.
  I have no experience with the chakrum but, I'm sure, like all blade weapons it is one of finesse and technique, not power.
  EXAMPLE: Take your sharp pocketknife (you DO keep it sharp, don't you?) press the point against the palm of your free hand. now, with the hand holding the knife, flick your wrist down. Is your hand sliced open damn-near to the bone?
  Didn't take much, did it?

why dont YOU do it and show us DCR?

and six months down the line was she still using that as a blackmail bringing it up in disagreements
