Horror/Weapon Geografts and morphs G8/G9?

Just wondering what's out their to give a character an axe for a hand or chainsaw or scissor hands, things of that nature, for Halloween ideas of course. I'm interested in geografts that can have materials like a steel axe and wood handle, or even just geografts that give a shape, so like the arm could morph or graft to something, and I'd just apply my own shaders for ghastly or metal effects.

I know there are plenty of pumpkin heads. I'm personally leaning towards arm ideas. Thanks.

Also this pic could be one such example too, like tentacle weapons or appendages.
