Knives are dangerous. No argument there. Hell, my car keys can be dangerous too. But they are also utilitarian in a lot of different and innocent situations. Having a simple pocket knife is not a bad idea.
- Cutting open boxes
- Cutting wire or string or that flat plastic tie used in packing
- Stripping wire
- Dislodging items
- Scraping things
- Peeling apples
- Whittling
The point is, I’d be less concerned about somebody having a pocket knife than a gun. But, that may be because I’m from the South and it’s more common down here; not that guns aren’t common, but that knives are very common.
