Speak for yourself! If I had something that ugly-cool, it would never be out of arms-reach!

The over-arching theme of Bladeforums, and the entire gear and preparedness community is the "what if" scenario, so even though we've flogged that horse so many times that it's probably begun to enjoy the attention, it's actually part of what motivates our hobby. You could do 99% of knife chores with a scissors and a letter opener, but those are still tools that you choose to have with you for use.
What circumstances could land you in a "survival" scenario? How much knife do you think you'll need? Asking and answering questions about what should be in your ruck for a trip is a core component of "everyday carry". If I think I could end up swimming ashore or walking home, the chances that I will have a substantial cutting tool are pretty good. Though if you're really serious about your scenario-crafting, it's not too difficult to learn knapping.
