Description
This is a #10 Belgian coticule bout (“bout” = polygon), bonded to slate. Its “length” has been shaped to an aggressive ~6.5’Ø, with a ~25’Ø affect moving across its “width” which peaks around 89mm or so. You can use this to shape a razor or other fine knife’s bevel by moving with the edge perpendicular to the stone ‘length’, and then refine that edge by facing the razor 90° to the first step. Use the longest facet as a visual target, not the various angles on the stone; move the edge parallel to this facet for the most bevel-cutting, and move perpendicular to this facet for the longest imaginary wheel (and most action at the apex).
I suspect, but cannot prove, that it is either a “La Dressante” or a “La Veinette” coticule. Cutting speed with plain water is quite good.
The little slurry stone that’s included has been shaped a bit to be the opposite form as the bench stone. You can use it to generate a slurry on the first step and shaping your razor will be quick. Align the little stone’s longest facet with the longest facet on the bench stone, and you’ll feel their shapes couple.
