Futuristic Chain Sword

This design is based on an ancient/futuristic design. I wanted to replicate the futuristic design from "Zelda Skyward Sword", there was a section of the game where enemies used futuristic weapons but came from the past. Another reference i used was "Gears of War" and the chainsaws at the end of players guns.
I like how the design has the guard for the sword acts for the storage component for the sword and while it’s a futuristic design that the sword has a stone-based handle. It was pointed out to me that this type of grip is like some weapons from the game "Warhammer".
An aspect I’m unhappy with though is the grip for the sword too. It feels too heavy and bulky and while there is a handle I added to help with manoeuvrability (like a scythe), it appears useless when the weapon is too bulky.
