And now for the models:


(Ultra Hammer looks terrible, I know. :P)
I may or may not do the first hammer, that's up to you to decide.
Anyways, Super Hammer does 35 damage normally, but you can right click to swing the hammer around and do 70 damage.
Ultra Hammer does 45 damage normally, and you can right click to swing the hammer around and do 90 damage. The spin lasts longer but leaves you dizzy (immobilized) for 2 seconds after using.
If you are willing to script it you have to add animation and export the model. (Search for a thread in modification discussion by me to learn how to export it to blender, MtnDew wrote it somewhere in the post).
