Someone once told me that a man should never leave the house without the ability to cut and the ability to make fire.
I agree entirely, although I would expand ‘man’ to ‘human’ and also add the ability to undo either a slotted or Philips head screw.
at any given time I have up to three pocket knives, a multitool, and usually a block of magnesium with attached flint.
I have been mocked for this.
I have also been the only person with the ability to start a fire when trapped in a cabin in donner pass during a snowstorm… So suck it world!
