Here we are. Today I received my coticule and I couldn't help trying it. I placed the stone under a gentle stream of water in the sink in the kitchen and started x-stroke until I felt the resistance increase. Then I increased the water jet until the friction increased again. In the end I removed the insulating tape on the back of the razor and ran to shave. I can't say it has been the best so far but I was able to shave myself sufficiently. For today I am satisfied! Any advice of course is very welcome!
