I am not a big knife collector but just wanted to share that I love my opinels 6 and 8. Use theme both extensively for so many things. Between the two I have managed to sharpen the 6 extremely well. I have used same exact sharpening methods on 8 as well, and it is sharp, but the 6 seems to have a really nice razor sharp edge. Do you have the same experience? Any explanation? Again I love them both and plan to get 5 and 7 too.
