I suppose that on a thicker blade the grind would be closer to the spine at the same angle as the thinner 3/16ths.

Although I plan on keeping the 1311 no matter how it performs, I don't know what to expect for clearing and chopping close to the ground where there seems to be nothing but rocks around here. I have seen machetes used digging holes and after a few minutes with a file, they are back at work slashing.
