I do likewise, organizing by Warmth, Water, Welfare, and Way. The warmth bag has the emergency space blanket, paracord for lashing together a shelter, extra petroleum jelly smeared cotton balls besides what I carry on my person, and the magnesium fire starter besides the three other fire making methods carried on my person. The water bag has a folding 1 liter water bottle and bottle of purification tablets in addition to the filter bottle or canteen I carry. In the Welfare bag is a pocket first aid kit, half roll of TP, fishing hand line, multi-tool, and snares in addition to whatever firearms I'm carrying. The Way bag has a small flashlight, compass, and map of the area. Knife? yes, two, both always on my person. Overkill? Not when you consider that in the real wilderness where I go there is no such thing as 911. My survival is up to me. If this sounds like it came out of a book, it did. I wrote it.
