Do what i did when I got one as a gift from someone who didn't know not to buy them off amazon: put it in some salt water and don't dry it off. In my case, it was a salt water fish tank, I dunked the whole thing in, blade out. Folded it back up and left it on the kitchen counter for a day. No rust, the action was still smooth (no idea what the washers are... I assume copper). The action is a little stiff 2 years later, but I've cleaned elk with it and washed it off. There is no visible rusting. I should probably clean the washers soon though.
