Peter--
I have carried a Griptillian Axis Lock for almost 10 years, and like it very much "now." The first blade in it was half-serrated, and it was difficult to re-establish a factory-like edge on the serrations, and I found that the straight portion did not retain an edge to my liking, so I sent it back and for $25 they put in a new blade without serrations.
I do find that I have to be careful with this knife--when handling it or if it is dropped, the Axis Lock will allow momentum to flip the blade open at least part way. Makes me honor the old saying about not trying to catch a falling knife.
The rear hooked blade on your knife looks suitable for cutting a seat belt, and hunters might consider it as a "gut hook" (which in fact should be called a "paunch opener" since the sharpened versions of such an implement is better suited for ripping open the hide of an animal). For cutting rope, I think the main blade, especially if it had the factory edge on some serrations, would be the best cutter.
