Weldalite is an alloy of aluminium that is about twice as strong as some of the aircraft grade aluminiums and around that of some stainless steels.

Although I have removed more weight from the design than I have added with the weight holes I can pretty easily thicken up the disc supports if need be and it needs a redesign to make it look more scary.

I'm thinking of calling it Shego after the character from the awesome show, Kim Possible due to them both being green, black and very destructive.
