Has Anyone Ever Honed With a Lydian Stone?
In his 1890 Geological Survey, Griswold refers to the Lydian Stone, which is primarily used as a touchstone for testing the purity and quality of precious metals. However, in describing the stone, it is mentioned that it meets all the criteria of a whetstone, only having a much finer grit. The area of origin is given as Asia Minor, but given that the stone had been in use for a number of centuries before it was mentioned by Linnaeus, I'm willing to concede that the original source may be depleted. Just wondered if anyone had any experience with using this type of stone as a hone.
Kindest regards,
