Thread: Honing Stone Identity

Hi members; recently purchased the following Natural Stone from the U.K. It measures 8" x 2" x 1 7/"8 - 1 5/8". Weighted at 1.488 kg. Stone was in a real mess when I received it making early identification difficult.



I flattened the stone on all faces using 220 sic powder over a float glass, followed up by 400 grit w&d. That revealed the following features;



The stone works best using water, as honing oil dampens the cut of the stone to severely. The stone is difficult to work up a slurry, but what there is milky white, and of a extremely fine grit. After working the primary bevel on a 1" woodwork chisel, my gut feel is the stone is 12000 grit +. The following shows the bevel of the chisel after being worked on the stone.



My initial thoughts are this stone may be a Tam O Shanter, but its a difficult stone to identify.

Any feedback would be appreciated;
