I've had the bic fail too often (over a 40 year time period). 60 below-- (but few people will see that) but had them break, had the wheel not spin, and lost them. Had them unable to work in the wind, unable to get the flame into my kindling pile. 'Modern simple sure thing,' is difficult to come up with and is an opinion. I carry paper matches in small zip locks bags in more than one pocket and in all containers I have with me... along with a vial of waste oil and or strip of rubber tubing that lights and does not go out. Will get wet or large inferior kindling burning in an emergency. I've had my boat sink and able to grab 'one bag.' I've had my hands wet and to cold to spin a zippo wheel. A match can be easier to handle is such emergency situations. Knowledge of all the various ways to start a fire is helpful. I have started a fire with my gun, with the spark plug of my snow machine. Much depends of coarse on the kinds of situations you could end up in. I sort of like the new electric lighters that charge off a usb port (or off my boat, snow machine, ATV etc) works in rain wind cold etc. Still, 'one item' can get lost or fail. I carry chemical hand warmers, (If 'fire' is for warmth) Warm hands can start a fire better. Some thoughts. Good luck
