Vintage Beige Grainy Sharpening Stone 7 1/4" x 1 5/8"

Unsure as to what this is, certainly natural and looks possibley like a Belgium coticule but those are normally more smooth and without grains on a slate.

Never-the-less a nice looking stone with the odd chip to the sides.

Only box base, no lide, and one end of the box missing as seen.

Looks pretty flat, no major dips.

No attempt has been made to get this out of the box.
