Colin, I was going to call you, as you suggested. However, I went ahead and bought a DMT diamond rod and tried it on the titanium La Griffe. That was the way to go. I don't know why the ceramic stones wouldn't work by themselves. I used the DMT diamond rod and brought the edge in and the gave the edge a few very light strokes on the fine ceramic triangle. The edge is just shy being truly razor sharp. It takes hair of the arm, but there is still some drag in it. I have improved the edge to the best of my ability. as my sharpening skills improve, I might be able to get the edge even better. As it is, I am truly happy.
Jason, thanks for not taking me up on that offer I made. I like this La Griffe too much now that it has a real edge to it.
It looks like I'll have to get a titanium Commander now.
