My experience in the field showed me that satin finished blades (not mirror finished) are far and away easier to take care of and are not as prone to rust.

Les, doesn't the steel make a difference in "care of the knife" and rust protection? Yeah, satin is best for protection, but with good steel (say 154cm), doesn't a bead blast hold up fine?
