I'm a Prepper, and I have a habit of sometimes having redundant blades. The big knife is also a saw for cutting wood, or other things as needed, the smaller blade is a good utility / survival knife and a good fillet knife when needed, the others are just spares and for smaller needs, i.e. cutting string or rope without having to break out the big knives, and, of course, that bundle is paracord covering a fishing kit, and my leatherman is a multi-tool, and the small yellow blade has a very bright flashlight in it, and that silver pouch is a fire-starter kit, etc. This is just my small, carry-with-me prep kit. That's all.
