I used too but, no longer. A good wipedown even with tree leaf's green or dead will prevent the rust until you get home & rinse it off & oil it. I think too many people fear rust like I used to but, it dosn't happen that quickly Folk's! I had a wet knife I stored in a leather sheath a long time ago & left it for months. It was rusted real bad but, it was my fault! So, do you knife users fear rust?
