I had a year to do a lot of research for this project. I decided to go into a prison and see how it works. While I was in there, I managed to see real contraband weapons that the inmates had managed to make. I also got to see/find out how they smuggle them around the prison with so many guards about. The most common way was in bibles. What they did was cut the bible/book inside to the shape and depth of there weapon, this was to ensure it was hidden and not bulking out.
