If by "fin" you mean removing a wire edge, I'm not talking about that; I'm referring to creating a clean and straight edge in very short order with simultaneously removing micro-chips and nicks to vintage razor edges thereby making the edge ready for bevel setting rather than honing and honing until the chips are gone. IME both methods accomplish the same thing and in roughly the same amount of time, it's just a different way of doing things. Wire edges would easily be removed in the same manner.

Sorry, I brought this post off topic in bringing this up in the first place. Shame on me!
