Hi, Richard and Others
"Turkey" fits the description of Belgian stones, known there as
"coticule". They are always used with water rather than oil and were used
to hone straight razors. Does anyone know if they are (geologically) the
same as Turkey? Where did Turkey stones originate? I gather that the
quarries for coticule have about run out now, but I have several of the
stones and treasure them.
By the way, I also have what is, apparently, a Charnley forest
stone that I inherited. I've never used it but keep it around mostly
because it is in such a pretty mahogany box.
