No, not yet. When it is time I am sending it to Dave. You can tell by the thin slices of pastrami that it is still razor sharp. I was told the white would hold an edge longer. It is not a knife I use every day, I pull it out when I need something really sharp or taking some nice food pictures. I have had it for 4 years now. The first year I was afraid to use it and mess up the finish, but I got over it and am using it more now.That's a beautiful knife. Have you sharpened it yet?
