Thread: Books on natural hones?

Are there any books out there on the history of natural hones? thinking specifically western-mined stones like coticules, arkies, CF's, thuri's, etc...
I haven't come across much other than small excerpts from articles and geological articles. Anyone have some good reads about these stones?

There was a man named Henke Bos that did massive research, complete with travel and in depth investigation into natural hones. His work is very highly regarded. He did not publish on paper though, but he work is still available.
