I been using a 40 degree inclusive edge on mine. I prefer a V edge over a convex, but that is each persons choice to make.
Thin cuts. It doesn't take to over the top hard use though. The "wider" the edge, the more surface area you have dragging on the media you are cutting, thus, wearing more of the metal, but with a thinner edge, you also get less separation of the material, i.e. "wedge" so you might feel more drag.
I personally like the thinner edge on cutting knives, and a thicker on on the beaters.
A 30 degree inclusive edge on a crafter and food prepper should be awesome. Just be careful, thinner edges roll a little more often.
