I have to say living in a village in England, having a garden full of vegetables, doing lots of DIY work, building a wendy house and (as I said before) going for hikes I've actually never actually had use for a knife. When are they required for you folk who carry them daily? And I don't just mean a cutlery knife. Even as a tool I've never had to use one outside of a kitchen.
Secateurs, shears, scissors and other pointy things that funnily enough all begin with S but never a knife.
I use mine mostly for cutting seals off trailers when delivering to customers, this happens almost daily. I also use it occasionally to cut/repair air lines on trailers.
When I worked concerts I used it to cut zip ties and e-tape or gaff tape during the load out.
When I worked in a warehouse I used it to open packages.
As a kid I used knives, and other large cutting tools, as I wandered the woods behind my parents cabin. I was swinging a machete by about age 10-11.
