I hope to find a soft coarse one eventually. I love good razor stone but those workhorse naturals on the coarser end are something special to find. I've got a REALLY coarse charnley(probably a little coarser than my Grecian llyn idwal) that I need to flatten a lot. I have a feeling it will Beeville one of my favorite knife stones. My other medium coarse charnwood is an amazing knife stone.
