Very coarse belt finishes, 80 grit sanding belts, x-coarse DMT, 200 grit waterstones, etc., produce edges which have a very high slicing sharpness and long edge retention by simply creating a small saw along the edge of knives. In the most extreme cases the teeth will just be at the point of being visible, it depends on the angle of the edge as well.
Recently I have done some work basically making micro-serrations with fine hones. Take a sharpmaker medium rod for example, and using the corner, sharpen directly in one place on the stone to create a very small tooth, smaller even than the Cold Steel teeth. These little teeth are much more aggressive than the finish left by the rods directly.
Now I would not claim these are ideal solutions, but they have some interesting properties. They are for example much more durable under impacts and push cutting that just a more coarse finish from a stone, however they are more difficult to resharpen optimally and plus you have to do it in two stages. First create the primary edge and then the little teeth.
However if you do need to get more aggression than the stone can provide they can work well. You can also use the corner of a file to do the same on machetes and thus give an inch or so of very rough mini-serrations than will continue to cut long past the blade would have been blunted by chopping.
