The thinner hollow grind edge is precisely for heavy duty chopping...: Its thinness softens the blow on the hand (as does the concave curvature during the deceleration), and the wood pinches the blade away from the edge (unlike a convex edge), making the edge both thinner and stronger to lateral loads than an equivalent convex edge...
With a thin, deeply radiused hollow grind (but with a saber line not much more than halfway up the blade, which is a disadvantage for very deep straight through cuts) you can get both slicing and chopping in one edge.
The worst versatility is the convex grind, because it imitates a hatchet, so it has to be thickened at the edge, or it will warp to lateral loads from which a hollow grind won't. Here a fairly thick edged Busse Battlesaw could not match the stability of even a thinner V-grind in 5160:
Full Flat grinds tend to "stick" on serious choppers over 17 ounces, so that is their limitation... This is because the flat surface has no sharp "point of pressure", so the leverage of friction is spread over a broad surface, which makes it harder to break the "hold"... Wet wood multiplies this by ten btw...
Mind you, a hatchet does greatly soften the blow on the hand by being so out of balance, but it has virtually no quality outside of that. (It does help over a prolonged period of use, but that is about it).
