The $4 Mjolnir (for those who are worthy, but broke)

Hello all!
For the last few weeks I've been doing some preliminary work on an "Avengers" style Thor costume (hopefully I will have those duds ready in time for the premiere of the new movie) and the first thing to get off the table was everybody's favorite Asgardian thwappin' stick, Mjolnir. I am trying to keep the cost as low as possible for this build, so I didn't want to buy a hammer if I didn't have to. 95% of this hammer was made from stuff I already had, so the total cost was 4 bucks. Yeeha!
This hammer is sort of a hybrid Mjolnir, blending the look of the movie hammer with the comic hammer. I really love the idea of Mjolnir being a little rougher in appearance to reflect its years of bashing cosmic evil in the teeth, so I went for a dirtier more "forged" look for the head and omitted the knotwork panels on the sides of the bevels more out of necessity that anything else. I may add them later on if I can find the time. The grip and pommel are pretty much straight out of the movie. I loved the pommel design on the "Dark World" hammer, so I borrowed some from that.

The head of the hammer is eight pieces of blue Tyvek foam sandwicheded together. I cut and sanded the block into shape and then glued on corresponding pieces of EVA foam (bought from Hobby lobby, hence the $4) and filled in the gaps with bondo and hot glue. The handle is a length of PVC pipe with an internal dowel for weight and strength. I wrapped it in leather left over from an old leather jacket I had lying around. The grips were just long strips of EVA foam I painted and glued on, bending them in shape as I went. In all honesty, I'll probably redo them. The pommel and accompanying knotwork are EVA foam and the strap is part of an old leather belt.

This hammer was intended to be light enough for me to carry around all day but be tough enough to withstand the rigors of trooping. I've tossed it, hit stuff with it, dropped it, spun it and chucked it and it held up like a champ! This was a fun and gratifying build, and I can hardly wait until I have the rest of the outfit to complete the look. 
Thanks for reading!
