So being the artist I decided some time after having a pair of Glaives in game  that I wanted to make a set   SO  here are my final results  after a few months working on them off and on.
I have plenty more photos  if you all want to see  but here is a couple
So let me know what you think    Keep in mind  I did not follow the blizzard design 100% but they are close enough
They are Fiberglass resin cast and each weight about 8lbs
ADDED pics    here is the casting process  figured people would love to see it
Pink foam positives were then cast in Silicon and then the halfs of each blade were poured and then assembled
Blade Halfs
Raw resin cast half
Whole  raw primed Glaive
Finished
