Two layers, thin fine lighter one, thicker coarse dark one, woodgrain pattern, wood box, 'soap stone' - naturally my mind wandered to the possibility of a vintage Belgian. Just the strange deep hollow in the would-be BBW side was a bit odd. Then again, people maltreat their hones in every possible way. At less than 5 Euro well worth a try.
