Yes, Trenchy, remember that a good, sharp bevel is an absolute requirement before moving up in grits. A bevel can be accomplished with ,say, a 4k stone, but it will take forever sometimes! ;)
Razors from antique stores and Ebay have usually been inactive for a long while. No telling who has done what to them in the past. Always best to tape the spine and dig out YOUR sharp bevel before proceeding.
