I don't have any Black coated Benchmades, but the coating on my Carnivore seems to have held up well. I don't really have anything to compare it to. I do know that Walter Birdsong is the person who puts the coating on. I don't know if that helps any. If you get a black coated REKAT, let us know how it compares to some of the coatings.
