I have one , but havent used it much yet, ive found that soaking the blade in breakfree for a couple days will help it resist rust for a about two months, you still need to keep it dry, but it makes a difference when carrying it in damp enviroments, i do this to all my beadblasted blades. aside from aus6m, cpmv 440 will also rust if its a beadblasted blade. this happened on my first kershaw avalanche.
