I am seeing some kind of traditional divide here. The European and the North American way of choosing a knife, though it is not that obvious in this particular discussion.
The European "survival knife" is a development of the classic Mora knife and the Sami knives. Quite short, 3,5-4" blade, low hanging leather sheath, relatively low grade carbon steel (compared to modern super duper steels), handmade, no fancy things whatsoever. Basically the work knife you wear every day. Look at a modern plastic handled Mora knife and the Fallkniven F1. They look almost the same. It could also be that they are "outdoor" survival knives. You cut some wood, rope, fish, animals and such. Rarely some harder things. You use an axe for harder work.
The North American "survival knife" is sometimes a development from the Bowie knife, bigger blade (6" and up), tougher looking knife, leg straps, modern knives usually have serrations and other "cool" gizmoes on them. They are primarily "combat survival" knives.
A quick example. Fallkniven F1 and Gerber LMF II are developed for survival. The big different in size, style, sheaths and whatnot is that when the F1 starts to see use the pilot has already landed on the ground and has to "survive" the elements. Usually a jet pilot ejecting over friendly Sweden

The LMF II is made to break glass, cut straps, saw through fuselage etc. It might do that very good, mine just cuts fingers very well.
So by just looking ath the knives you come to the conclusion that Swedish pilots eject before the plane crashes, US pilots cut their way out when it has landed
One way to figure out which knife you want is to get both (or in extreme cases make a mockup of one) to see which one you like to carry around most. Thinking about it I realise that last time we were walking in the reservation, I had my fancy survival knife in a pocket on the back of my backpack, not hanging in my belt. My "excuse" was that we were four people and not more than five km from a road and we had cell coverage. I dont like things in my trouser pockets. It might because of my figure. The thigs press on whatever is in the pockets and it starts to chafe.
