A few weeks ago I got a message from Renee saying that the grind height on the combat grade SOD is the same as the CGDF. With that in mind, it is still a fairly high saber grind. To me, an all purpose camp/survival knife should have a high saber grind because of the added strength. For the SOD, a high saber grind may also make it a better chopper due to the more blade heavy weight distribution. Anyway, that's my opinion. If I could, I would just get both, but due to financial restrictions, I only ordered the tan SOD.
