Anyone have experience with the Kabar Dozier 4059 in D2? I had one, took it apart, put it back together, but somehow lost a washer. I forget what ended up happening with the knife, but now I want another, and I never really got to use mine and so I'm still looking for experiences with it. I also never had to sharpen it, so I'm wondering how the heat treat on the D2 is, and how well does it sharpen on a Spyderco Sharpmaker? Pics are always appreciated, as well.
