Rusty knife

This knife was purchased from a costume store and was generally cheap looking. First, several gashes and scratches were carved into the face using various files to give a very used aesthetic. Then it was painted with a very shiny chrome silver spray paint. After that, several passes of weathering were put over the silver. A pass of each black, brown, and tan paints and a few passes of reds, oranges, and browns with layers of salt in between were used to give the rusting effect.
