That multi-bladed weapon is the axe of choice for Copy of Elite Watanabe Enforcer E by Papsikels from We Print Miniatures. Luckily Enforcer E has a sturdy shield to prevent it decapitating itself by mistake. Surly, but will do as it's told on a good day.
This miniature is provided in 32mm scale and as originally designed by Papsikels Miniatures, this is their artistic work without addition or alteration, forming a fascinating collection that you can now own at home.
