I agree, but would suggest that if someone is forthcoming with their methods, I would feel better inclined to critique (personally and privately) their results relative to the methods used.
If I ever test shaved with a "secret" hone blade (and I doubt I ever would...unless it was a trusted friend that has previously demonstrated his/her craft and hopes to get an unbiased review of a new method they are attempting), it better be pretty amazing otherwise I would have to roll my eyes a bit as to why the secrecy behind a lackluster result.
Simply put, a master can get away with cagey behavior....the rest of us would only raise suspicion and high scrutiny with such antics. Oddly enough, those that have truly mastered honing seem (for the most part) to be quite forthcoming with their methods in my experience;)
