The sog is a thick heavy duty blade, that while I have never used it can tell you will not cut food well, will not slide through nylon rope as easy and do small tasks nearly as well as the spyderco.
The spyderco has a much thinner edge and will slice like crazy But it is not a blade you want pound through a log to split it. The sog might be. I personally am getting pretty sick of thick knives, because all these super heavy duty tasks they are made for, never seem to present themselves to me, and they only cut through rope,cardboard, small branches etc, with much greater effort than thinner edges on less stout blades.
Also the Sog Blade is around 5.5 long. Not a chopper. So that only leaves the smaller tasks which I think the spyderco fixed blades are better at. To do everything, what you need is something heavy duty like a BK-9 or 7 for wood cutting, then the Perrin. I would consider the temperance fixed blade by spyderco as well if I were you. Both are great slicers. So are spyderco Moran fixed blade. The drop point works best for general use. Buy the Moran fixed blade drop point, the Becker BK-7 or BK-9 and you got it. For about 120 bucks total.
