I have this knife and have used it in the field. I'd have to agree with desidog, though: it's an adequate knife, but I'd rather carry dedicated blades. 440A is a decent steel, but I'd rather it be AUS8 or something with some vanadium in it. The saw is functional as a bone saw, but works a lot better on wood than a pelvis or sternum. The gut hook is too small, and the blade as well.
Since you can't have everything, I ended up buying the Kershaw Alaskan set. The steels are decent, albeit not AUS8 or 8Cr15MoV, but it's still made in China, as is the SOG (Americans don't make much anymore). Nevertheless, it has three dedicated blades: a skinner, a huge gut hook with a nice blade opposite, and a bone saw. It's bulkier than the SOG, but it's great to have when processing game in the field. I broke the saw the first time I used it, which ticked me off, but Kershaw replaced it no questions - they just sent me a new one. That was 2003, and I've been using it ever since.
If you are seriously tight for space in your pack or on your belt, the SOG will work, but you'll wish you had something like the Alaskan. Price of both are comparable. SOG would only qualify as a back-up, or a second blade to use with somebody coming to help me process my kill, who didn't have enough sense to pack a knife, saw, and gut hook of their own.
