Kirkhammer

Kirkhammer from Bloodborne. My personal favorite weapon although I have not gotten the opportunity to try anything in the dlc...
Built life size and the inside of the hammer is cut out so the sword can be inserted. I did not implement any sort of locking mechanism but the fit is tight enough it would probably stay in just with friction.
Needless to say its huge so you will need to downscale if you want to print it, the sword requires support material... The hammer should be printable without support material if placed upside down with the exception of where it meets with the sword.
