I have seen references made on other onsite sources classifying both Charnley Forest and Llyn Idwell Grecian Hones as Novaculite. imo both these stones would be better classified as a Chert.
Chert vs Novaculite
Any other members have an opinion on this subject.
Also; with regards the most commonly used natural honing stones, past and present, has anyone put together a listing that places each of these stones within a known category. eg; Sandstone; Slate; Chert; or Novaculite.
As an example; Arkansas, Washita, and possibly genuine Turkey Stone's would fall within the category of Novaculite.
