Yeah, I EDC a lighter and haven't used it in 5+ years. Still...
I was having a nice kidless dinner with my wife one night at the restaurant where we first met and the candle on our table wasn't lit. My wife was impressed when I whipped out the lighter and gave us instant atmosphere. She knows that carrying some EDC stuff i handy. She just doesn't like to lug too much around herself.
But I did get her to EDC a small SAK, a small light and whistle. It's a start and she has been carrying that little bit of kit for several years now.
