I bought an unlabeled La luna from a french guy who was selling coticules on Ebay. He had pictures of himself holding the cotis in front of his stone collection and I noticed 2 or 3 labeled La Lunas in the back round so I go his email address an asked him if he wanted to sell one. He replied saying that the labeled ones were not for sale but he had an unlabeled extra fine one which he said was about a 12000 grit.he would sell for $100. He sent me pictures of the one that was for sale along with pictures of labeled ones to demonstrate that they were the same - same saw marks and same glittery honing surface. I sent him the 100 buck then I did not hear from several him due to the huge storm in France which cut power to a large part of the country but yesterday the stone showed up. I put a Filamonica 13 that was coticule sharp on the stone for about 6 to 8 laps with water and the razor got way sharper. When I shaved with it I got an incredibly close but rather harsh shave. I read the post about using it with oil so today I dispatched my wife to the sewing machine store she uses to pick up some oil. As with most things there seems to be a learning curve with a La Luna. I attempted to upload the pictures but the JPEG files are to big and I don't know how to work around that.
