What type of grind/bevel does this blade have?

1:35 in the video.

Looks like hollow grind or scandi. What blade steel, sharpening grit and grind would work best for leatherwork shown in the video and why?

It looks like he is using a standard x-acto knife with a concave curved blade for leather cutting:

Here is a good link from BF: http://www.bladeforums.com/forums/s...d-knife-for-my-father?p=11149798#post11149798

For cutting leather without tearing, you want a very thin edge, thin blade, narrow for ease of control, and high polish. That's it. Don't need to spend much, any hobby knife will do and can be given a concave curve if desired.

Tandy leather sells an example of the knife in the video which is nothing more than a similar blade to that curved exacto but with a brass and wooden handle. Basically just an expensive and fancy hobby knife. I just use a razor knife when I cut leather as it's cheap and readily available.
