For a while my friend has been telling me to buy a zippo lighter to replace my survival lighter that will not light in cold weather. So far I like my zippo a lot better. Incase I get lost I have extra lighter flints in the part where you put lighter fluid, even after I run out of fuel the flints could save my life. The windscreen around the wick has kept it burning on very windy mountains. There are a lot of accesories you can buy for zippo. Zippo has had the same lighter design for 75 years and its been used in WWII Korea and Vietnam.
