Can some of you help me to understand the purpose for having a lanyard on a fixed blade survival knife? I don;t get it.

I know what a lanyard is. I can imagine a few uses: tying off the knife to your wrist or elsewhere if you're working with it in a place where, if it fell, it would damage it or be lost forever; hanging it from a branch near where you're working on a project (skinning or dressing an animal); etc. But aside from that, I can't imagine using a lanyard.

Some of the fixed blades I've seen will have 6" of lanyard hanging from the rear tang. I don;t get it.

Please help with your insight.
Thanks
