A while back I picked up a CRKT M16-14ZSF. Keep it in the truck for general use. Then it started rusting or corroding or something, seen this before in other posts before where some guys knives are just fine and others are rusting setting in the drawer. So today I was at the INGO swap meet and talking to Billybob44 and ask him what he used for rust. He showed me this stuff called FLITZ, a polishing compound, just rubbed it on the blade and it really worked. Have tried many things to stop the "stuff" on the blade but no success this FLITZ worked.
