I don't understand 'the people interested in them' being 'a problem.' Can you elaborate?
For the record I would have liked very much to use the two natural hones you mentioned above, especially the Escher. But they are above my pay grade and I now have an excellent series of synthetic hones with the SG 20k my finisher. I have no intention of acquiring more hones, probably no more razors either. This is not some proclamation it is simple math and something called fixed income.
