The zero grind/scandi grind gives you a finer edge than a standard grind that is also easy to sharpen. There are people out there who want a scandi grind on anything, but it is really best suited to small blades that are going to do a lot of slicing/cutting. Because of how fine the edge can get, it wouldn't be very good on a knife that you are going to chop with, because you are in danger of rolling the edge. Of course, it's easy to put the edge back on, but why bother when a nice convex secondary bevel chops very well without having to worry about the edge.
