Hey Guys, so, I am making a film series and needed a knife for one of the characters. Today at a flea market I found a cool Survival Knife for $2.50 and I want to cast it as it is not safe for a movie in it's current state. It is this knife, but different coloring (black handle, silver blade) http://www.amazon.com/Aitor-Jungle-Fixed-Blade-Handle/dp/B009QAIZSO Anyways, I need help figuring out how to mold it, and preferably for cheap, as more props are still needed for the film. Thanks! Please post cheapest methods you know!
