I've got an irreplaceable self made knife that is just starting to rust. I use some kind of anti-rust/cleaning oil and I've tried to brush off the rust as best i could without damaging it. I still want to use the knife but i want to preserve it as best i can without spending too much money on it. I just got the idea to put rice in the quiver to keep it dry in order to prevent further rusting. is it a good idea and does anyone have any other good tricks to hunting/whittle knife maintenance?
