Mine are a whole category of forks and spoons. I want my forks and spoons to have a completely flat underside with rounded corners. The underside should not be concave because it makes the edges of the fork or spoon too sharp and dig into my finger bones too much. A convex underside puts too much weight onto the center of the surface making it uncomfortable for my middle finger then as well. Oh, and they have to be completely smooth with no texture because I don’t like rough textures rubbing against my fingers while I eat.
