I searched but couldn't find any info on this stone on the forum. My local knife emporium carries these as well as Shun stones and Zwilling Kramer glass stones and I was wondering if this might be worthwhile. My current synths are shapton pros and I have 1,2,5 & 11K. I know many think the SPs are actually lower grit than advertised. Anyway. Price isn't terrible. Just curious if anyone had experience with the Wusthof.
