I think he's referring to the blade shape, not the grinds; specifically the top front portion of the blade on both models. The scoop of the clip on the 17 can be considered concave (curving, or hollowed, inward), and the "bow" formed by the late drop on the 16 would be convex (curving, or extending, outward). Making either aspect less extreme - as shown in posts 35 and 38 - is a modification that seems to be appreciated.
