By " compares to the current crop of survival knives", do you mean the Ramboesque flea-market knives, or perhaps the Chris Reeves Aviator, or something else?
I have a Ontario PSK, a Kabar Marine knife amd a Fallkniven S1, which I believe all of these are in the "survival knife" category. These are military-issue fixed blades over 5 inches, designed for heavy use and combat. I know others (myself included) consider a "survival knife" is any knife (or knives) that you have on your person in a "survival event" (i.e. your car breaks down in middle of nowhere, hurricane hits your town, etc.).
On with the review:
For its price I think the PSK is a good knife; sturdy, easily sharpened, ready-modified (lash-holes on crossguard, sawback), useful in the field. However, it does try to be everything that a R&D committee could think a pilot would need in a survival situation. It does everything OK at the price of doing any one thing not so well. For example, the sawback isn't very good for sawing wood, the crossgaurd cuts into the hand during extended use, the blade is thicker than would be good for carving wood, and it's shorter than I'd like for a fighting knife.
Compared with the Marine Kabar, they are both carbon steel, the Kabar is longer, the handle is easier to hold. Compared with the Fallkniven S1, the S1 is nearly the same sixe, doesn't have the sawback (but it isn't needed as the nordic style of chopping wood involves "batoning" the knife into the tree limb), has a comfortable synthetic rubber handle with protruding tang, and is made from VG-10 stainless.
I don't know how much this helps, as there seem to be two "schools of thought" when it comes to survival knives: first, the big knife school, which prefers a large (7"+) fixed blade; second, the folder or Swiss Army knife school, which prefers a SAK or similar multi-tool knives. Each has its pros and cons by my reckoning; that's why I tend to carry more that one knife at any given time. Right now, for instance, I have a Wenger SAW Soldier, a Wenger SAK Esquire, a Mora Frosts Swedish Army knife, and a Camillus ArcLite "Ol' Glory" neck knife. I don't get out of bed without putting on the ArcLite, as it also has a Inova LED, as my "preparedness kit."
