Norn hand axe from Guild Wars 2. All it's missing is some feathers and leather straps =D
Attached the pieces and the full scale stl for your enjoyment. Pieces all key together, and a 1/4" thick metal rod can slot through the handle for extra resilience.
Feel free to ask for edits or offer up other fun prop ideas. =)
P.S. Be advised the single model axe version is scaled down by x4, because I was dumb and wasn't checking my sizes when I started.
I make a little bit of everything. Normally my 3D models are props intended for conventions or theatres, but occasionally fill other roles as well.
