No.
Many people who do "real work" in factories never touch a knife at all.
Many people eat food without ever using a knife. Packaging has become "knifeless" in many cases, and more and more food comes portioned off.
I like knives more than is healthy according to much of the population.
I go out into the woods despite being allergic to mosquito bites mainly to be able to use more of my knives more...this does not stop me from seeing reality.
And the reality is that many people go through many days just fine without use of a knife.
It's a good idea to carry one anyway as it is very handy for certain applications, but those application are not very frequent for a great many millions upon millions of people.
Of course, I also find days that go by where my cellphone does not leave my pocket to be used...except to take a picture of a knife that also saw no use that day.
When working as a machinist I had a knife in my tool box, but it was the least used of my tools, other than the dial indicator used to get the Bridgeport milling machine table perfectly level. That got used about the same amount. Both were handy tools when needed, but weren't needed all that frequently.
When working in a lab I got to use my knife more, and that was cool. Others made due with scissors held open and used as a knife, or the old, dull as hell box cutter in the drawer. Every so often a sharp knife was needed and then I was "Hero of the Lab!!!"
Now in the quarantine days, sometimes I used a knife to assist in the kitchen, but really I'm just getting ion the way of my wife.
