I've done my risk assessments and based me "bob" on likely situations for one thing. For example I see the house fire or tornado happening. For those I grab the bob and use it or the knife to get through the window to get out of the house (fire) or in the case of the tornado shelter in the basement and the tools can be used to cut our way out of the damaged house afterward if needed.
The 'head for then hills' situation is highly unlikely but I already have the tools for that. I own 80 acres of 'wild' that I would go to. Its 250 miles away so it may involve sheltering along the way. I'd be using the truck camper most likely.

The secondary reasoning is these are my outdoor/camping bags and tools so those tools are kept there, its partly just for organization.

I see a lot of people put a Stanley Fuber in their urban bob.
