The proof is in the finish it provides, as good or better that a quality fine Thüringen.

These stones are still somewhat of a mystery as to their origins. No doubt they are finishers and I find it most interesting that they were used as backers to Coticules, perhaps as dual grit hones.
Surprisingly they are still floating about in the wild. I picked up a small 1.5X6 a year ago at a swap meet for $2.
