In any case, I can tell you that edge geometry can allow a dull knife to keep cutting. I once tried to cut a very small honeycrisp apple with my Dozier Buffalo River Hunter, and quite literally had to force my way through. When I was done, I had to drop a tomato on the blade just to make sure the knife didn't suddenly dull on me. To my surprise, the tomato was split clean in half. It seems the blade was thicker than I expected, and couldn't cut the apple very well because of it. Same with corn, and my ZT 0551 also proved difficult to use on apples.
The edge would push cut paper, but I really had to muscle the Dozier blade through the corn, which presents a significant risk to ones fingers, cutting glove or not. Compare it to my coworker's knife which would regularly tear paper, but could still slice through the corn stalk like butter because of the paper thin blade(closer to sheet metal than a knife blade).
