In a critical situation, I want tools and resources with which I am familiar and practiced. I am not a fan of tucking items away, out of sight, and then employing them only during emergencies.

Now there are lots of variations and exceptions, but in general, in a crisis you want to have resources you know to be reliable and not something unfamiliar. W can be talking about anything from climbing gear to first aid equipment to firearms, but familiarity is crucial to success.
