Mint condition with just some oil residue on one side. 2 1/4" round (stone) in a rubber holder. The rubber cap is marked fine on one side and coarse on the other. And it appears the two 'halves' are bonded together. Both sides are quite fine!
These apparently are not made anymore and impossible to find. From the web: " (It) sharpens like nobody’s business and adds a perfect smooth finish to your blade... They are made in Gotland Island in Sweden and the natural stone that was originally used to produce them with have been depleted."
