Whew! I wanted to give a knife in D2 a try, having been an ATS-34/154CM user and hearing good things about D2, and I picked up a Benchmade 201 Activator knife. It was sharp out-of-the-box, but not to my satisfaction.
Man, the reports that "D2 takes a poor edge and holds it forever" seem to make more sense now. I about started a fire-by-friction on my alumin-ceramic crock sticks with little progress on the edge. I went back to a diamond stick to set the angle and then back to the crocks. Finally, after 1,500 repetitions, I have a smooth edge that pops hair.
I'm thinking I may have to break down and invest in a Lansky Diamond Sharpener or the like. My Arkansas benchstones could probably strop a near-finished edge but I'd be forever should I need to get this one back from a nick or edge warp.
I'm really liking the Activator so far. It seems to be a good, general purpose hunting knife. Passed both the Hormel Pepperoni Test and the Garden Stake Pointing Test swimmingly but I'm afraid any deer work is still months away.
