I have been whittling with a BK24 in D2, and it is working fine. Good edge retention too. When I am home, I use my carbon steel Flexcut knives for detail work, because I can get a screaming sharp edge on them fairly easily. The D2 takes more time to sharpen, and I tend to say, "good enough" when I get tired of it snickering at my feeble attempts. If I had to choose, I would go with the D2 if I needed more working time between sharpening. I used the BK24 to baton a random chunk of wood into walking stick length, smack off the branches and knots, strip the bark, shape it, and rough scrape it without perceptibly affecting the edge. Mr. Becker makes good tools.
