I'll share this story here because I think it applies, and because it's a great story.
Back in December of 2020, a couple and their young child were driving here in my home town of San Diego when a gas can fell off the back of a truck in front of them. The gas can got wedged under their car, and before they could stop, sparks from the steel can scraping on the road caused the gas to burst into flames.
With the family's car now on fire, the driver stopped, and the parents tried desperately but unsuccessfully to free their toddler from the car seat in the back (defective latch).
A Marine from a local Marine base came upon the scene, pulled out his pocket knife, and cut the toddler free from the burning car, saving it's life.
You can read the story for yourself by Googling "San Diego Marine Saves Baby", the story received a lot of coverage here.
Now sure, this is an extreme example, and the chances of encountering such an occurrence are slim, but could you imagine, being in a situation where a mere pocket knife could make the difference between someone living or dying, maybe even a child, and you don't have a knife because you decided that you didn't
need a knife?
On a related note, I remember seeing a cell phone video of the immediate aftermath of a car accident. The driver was trapped by their seat belt in the smoking car. The first responder, an LEO, apparently didn't have any cutting tool and called out to the gathering crowd "Does anybody have a knife?!". I don't remember how it turned out.
Whether it's something as mundane as cutting open a package, or cutting the tag off an article of clothing, or whether it's a matter of life or death, the need for a knife isn't always something you can predict, sometimes the need for a knife
just happens.
But being on a knife forum, I'm sure that I'm preaching to the choir.
I never leave home without one (two actually. sometimes three

)
