I've had one of these for a while and never had any success with it. I happened to watch a video by @drmatt357 on maintaining an edge on your razor. Matt used an ILR in the video, but mentions a few other hones including a purple Welsh slate, so I thought why not give it a try with the so-called Welsh "Thuringian". After getting an edge on a N8k it only took about a dozen laps under running water for the blade to start sticking on the slate; I did about 20 more with light pressure and stropped. The shave was excellent.
This stone for me was one that had languished for years; sometimes being used as a holder for other stones. If you have one of these and have had trouble making it work give this a try.
I hope this helps someone.
