It might help to set some parameters of what tasks you might be required to do in a survival situation in your locale or wilderness areas you frequent. For example, what types of wood (if any) will you be needing to cut? What types of animals (fish or small game, big game, etc.) will you be needing to dress out for eating? What is the water situation like? In some forested areas, you can pick up enough small sized dead wood to make need of a hand-axe type knife unnecessary. In others, no. In some desert areas, there is no wood bigger than you pinky. Will you be needing to hack or cut into cacti and succulents to obtain water? If so, you want a long blade. There are "one size fits all" survival knives, but, often, you can tailor one to your particular locale and it can be better for you. The BK-9 seems to be the best "one size fits all" that would be good for most survival situations. But, you might want to take a look at the plant life and animal life in the areas you frequent and think how well it would work to render them into food, fuel, tools, and shelter. In other words, "see" what you might need to do and you will "see" the knife you need. Even if you have to spend a few more bucks, it's worth it to have the right tool for the job when the job is staying alive. Hope this helps.
