I have never used a Shapton hone of either kind but I saw RandyDance use ChrisL's Shapton Glass Stones for the first time at the MN meet up last year. It is obvious that they are fast cutters. Anyway, because of the discount being offered by Jende Industries, I am considering widening my hone options with a set or two of Shaptons. Now, I have a bit of an aversion to the Glass Stones because they are so thin. On the other hand, I believe they are considered by many to be great hones and I have read many praising comments about them.

I am wondering, how do they compare to the Shapton Professional series?

I don't know of anyone who has used both lines but I would welcome any comments about either line. I would especially appreciate comments from anyone who can comment on both lines. If it matters, despite all of my other toys, I'm interested in either line up to the 30k hone.
