To answer your question about removing all the patina. I have yet to use a chemical method that actually achieves this so I am not sure. I will have to put some thought into it. I am curious what you mean when you said the method may work "too well".
To get a feel for the cleaning process, find the nastiest, dirtiest-looking penny you can, and drop it into a small coffee cup with about an ounce or two of vinegar and about a half-teaspoon of salt (stir well before immersing the penny).
IMO I would not use it if that was my sword - provided it's original (which it appears to be from the photos), I sure wouldn't want to remove all that history.
