Sizes and shapes may vary. Consists of two layers: a Coticule seam (not every Coticule seam in our quarry is of the same thickness). And black slate. Tiny hairline cracks may be visible along the edges of the stone. This is perfectly normal for such a brittle material and it has no influence at all on the sharpening properties. Bulk packed.
