Final update for awhile? Finished modeling the axe. It will be four pieces. Two blades, shaft, and base. The shaft will be able to rotate around. The main blade is about 5cm long.

Below are the renders showing the main axe and along with my 3D Prime model. Please be aware, my Prime model isn’t 100% accurate to the toy. The battle axe’s base is shaped to match the actual toy though in terms of fitting.
