I don't know... many are very set against breadknifing but most of those will make the exception that it's appropriate in extreme cases and or for frowns/smiles. Seems the main argument against is that it may be unnecessary and result in more material being lost than necessary and/or a tremendous amount of extra work. All this in the context of newbies honing an unknown blade. Lots of you experienced guys (that's important) say that you have bread knifed blades in the past and would do so in the future if warranted. The key point being that you can tell if it's warranted.

What about the flip side? What about the following example:
Let's say I have my new blade that came shave ready so I know what the end goal is.
I have all my equipment and I've watched all the honing videos and read all the tutorials.
I get a quality brand razor off of eBay that's in very rough shape (rough enough that I know it's in rough shape).
So without pics, what's your advice?

I expect it would go something like "How rough is it?" to which the response would be "How do I tell?"... So isn't there any value in starting from a known condition?
