If I follow what you're saying, the Randall should be more resistant to rust than Reeve's knife based on carbon and chromium content. I haven't seen the issue as much as you suggest with the CPMS30V because of the blade coating and the oil I've been putting on the blade edge before each outing. This isn't ideal since it washes off and more importantly I don't want to contaminate the flesh of fish I'm going to eat with either oil or rust.
