Has anyone else had a rust problem with Case chrome vanadium blades? I didn't carry my three blade stockman at all and after having it sit in my room for a year there were rust spots all over it. Is this really supposed to happen? I didn't keep it regularly oiled but I also have had a CS Culloden with a Carbon V blade (which to my knowledge is known as a steel with very poor rust resistance) sitting in my room for a longer time and that has not rusted at all. I have only given the Culloden minimal care.
