Anybody using the lastest Shapton Rockstar hones?

Hi all

I wonder if there is anyone on the forum with any experience on the new Shapton Rockstars? These hones should resemble the glass series, but come in 1cm thickness without the glass back. The hones however should be more refined than the glass stones, with the 10K at 0.6? and the 16K at 0.5?, according to the online info on the knives&tools website here in Belgium. The price for these stones is interesting too, whith the 16K costing less than $100.

I read a very positive review on a German forum about someone using the 10K, but was hoping to get more feedback about the performance of these stones.

Kind regards

Peter.
