We need more upstanding citizens like you in this world.
It's so embarrassing if you threaten someone at knife point, did the whole "your wallet or your life" spiel and then figure out that you actually don't have your knife with you.
So a coworker at one point was selling this interesting odds and ends offered me a knife with a lighter on the other side. I did need a knife to open things but I had no real use for a lighter as I don't smoke but I of course bought it anyway because it was cool. Had this little dial to adjust the size of the flame... Fast forward to later that night bending over with a 6 inch flame coming out of my pocket from the end sticking out.
I don't smoke and don't carry matches or a lighter but have long hair (male) and regularly get asked for a sig and I say I don't smoke and I get this mean bullshit eye from these strangers.
