Just got a new Thuringian and tried it out last night on three razors. That thing is like honing on a stick of butter. It is incredibly smooth. I took the three razors (already shave ready) freshened on a coti with mild slurry, then to just water. After that I gave them about 50 strokes on the Thurni. It is a little small (5x1) but it is really nice.I have to take my time and lightly use a finger on the toe end to ensure I maintain contact throughout the stroke. Eventually I will get my stroke down on it, but until then I figure it is better to be safe than to not maintain contact. I will shave with them this weekend. I can't wait. I'll try to post pics soon.
