Nice looking tool you have there. The handle says it's got some use and the thumb stud has some nice wear. The tip of the blade looks worn also. I assume it's been sharpened several times at least. If so, CRK did a bummer of a job on that sharpening. At the top of the bevel near the middle you see what appears to be factory grind marks. At the bottom of the bevel by the heel you can see it was over ground. All of mine have had this to some degree and I leave a little after the first sharpening. It's just looks and they eventually sharpen out. Surprised to see them on a knife that looks so well used.
Also, what is that background?
