First off, holy crap that is awesome.
Secondly, I don't have any power tools personally but I can always borrow my old man's. Nothing fancy though. It says yours is made from rigid foam, paper mache and wood handles. Sounds easy enough. What tools did you use? Specifically, the part near the front handle?
Like I said, I'm a bit new to cosplaying and prop making in general (I only did one so far), so I wanted to do something a bit on the easy side.
