I carry a knife for the menial things that crop up that require simple cutting. Pretty boring stuff, but it comes in handy. Been doing it since I was a kid. About 50 years now. I never had to kill zombies, rescue people, defend myself or any of that interesting or fictional crap. I must lead a boring life. Thank God for the embellishers here to show me the true value of the mighty knife. I just like them and don't need to make shit up to validate my hobby.
