In my world, rust is just a flavorless spice that you don't need to plant or harvest or drive to the store to pick up. Every Old Hickory kitchen knife I own has a rusty "patina" on it and I use them every day.
My Scrapper 5 CG has seen its share of turkey and deer as well as plenty of beef and veggies and all I do is sponge wash it with the rest of the dishes and voila, its ready to pop back in the sheath once dry.
Rust puts the hairs on your chest bubba. <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />
