This is what the Polish eBay advertisement stated.
Dragon's tongue. The price was (is still) very interesting. 150 mm x 50 mm x 17.
The stone arrived last Wednesday and I worked it in the evening.
In the garage I found a slab of granite that had to be an old window sill (in Italy we use the granite in this way...) and I used it as backing plate.
For this lapping I bought some sheets of 600 sandpaper.
To attach it to the granite plate I didn't use a double sided tape but simpy water. I used the suction effect that creates the capillarity of the fluid. Once wet the paper was firmly fixed on the granite.
Then with a pencil I made some "X" on the top face of the stone in order to understand when it would become flat. I realized that using the paper 600 I needed all the night to finish the work. Too fine grit. I remembered to have some new 320 sheets and I tried them. Perfect. Once I made flat the central part of the face I remount the 600 and I finished. Then I focused on the edge.
I also gave some pass to the slurry stone.
Finally I took the razor and I gave some stroke on the stone "sharp leading edge".
Some pass on the strop and I made the usual test by cutting some arm hair "on the fly". Perfect!
I tried a shave. Outstanding. It seems almost like a cut shavette!
Thanks to Fabrizio for advices.
