This one-inch EDC Waterproof Lighter is known to outdoorsy types and survivalists as an "everyday carry." That means it’s designed to be useful at all times and in all situations—from the mundane to the disastrous. As such, it requires no maintenance. It also means it will probably save you some frustration and, depending on the type of day you’re having, could save your life.
This is the smallest, sturdiest lighter you'll find on the market. It’s made from high-grade stainless steel—the 300 series to be exact—meaning it has low iron content and is unlikely to rust.
The lighter has a hermetic seal that keeps water and air out—and lighter fuel in (so it never dries out). Even if you haven't used it for a year, when you open it, it'll still light up.
