Yeah, I have handled a Bionic 1.0, but the opinion of the 2.0 in comparison of the original is night and day, from what I've heard. D2 has it's trade-offs in my line of work, which is lots and lots of cardboard cutting. D2 will retain it's edge a lot longer, but it's gonna be hard to sharpen on the Sharpmaker. S35VN on the ZT 0808 is easier to sharpen but might dull on me by the end of the day.
I have a Leek with a composite D2 blade and I love the retention of D2 and haven't had any corrosion problems since I keep my blades coated in WD-40 to keep the blades clean of tape adhesive. But touching it up on the Sharpmaker is a nightmare. I have to go through the entire process of 20 passes on carbide, 30 passes on ceramic just to get a microbevel to show up. The S30V of my Para-2 only takes 20 passes on ceramic to get hair shaving sharpness back, but it tends to drag more through cardboard towards the end of the day, making cutting a little more uncomfortable.
So basically what I'm looking at is convenience vs. workability. Easy to sharpen and loss of edge vs edge retention and difficult, but less frequent sharpening. Trade-off seems to be nearly even.
