1) The Mark 2 will have more texture than the Mark 1 handle - I think the high res version of the rendering shows this up quite well. The anodising will also be of better quality (we by no means cut corners with the Mk.1 handle, but the company that anodised it didn't do a very good job).

2) In the words of Grandpa Simpson, a little from column A and a little from column B. You can grab it, just about, but it's designed to be spun around using the knobley bits. It works really well, and has a positive satisfying feel to it.
