The trench lighter: a flameless and windproof backup fire option
In our recent blog post about making char cloth, we discussed some of the limitations of this fire-starting material: it’s fragile and becomes useless when wet. Fortunately, there’s a practical solution that solves both issues — the trench lighter, also known as a “rope lighter†or “sailor’s lighter.â€
A trench lighter works by catching a spark in a charred section of a rope. Once lit, the charred fibers act like char cloth, creating an ember that can be used to start a fire or light a cigarette. The rope is typically encased in a metal tube, which protects the charred tip from damage and moisture. It also provides a way to snuff out the ember when it's no longer needed. Some models even include a built-in spark wheel for easier ignition.
Trench lighters have gone by many names over the years — sailor’s lighter, shepherd’s lighter, or chucknuck. Originally developed for sailors who needed a reliable way to light pipes in windy conditions at sea, these devices became popular during World War II. Soldiers used them in the trenches because they didn’t produce a visible flame, making them ideal for stealthy lighting in dark or dangerous environments.
Today, trench lighters are still valued by preppers and outdoor enthusiasts for their durability and reliability. While most survival experts recommend a BIC lighter, stormproof matches, and a ferro rod as primary fire-starting tools, the trench lighter is worth considering as a backup option. With practice, it can become a dependable tool in the right hands.

For those who enjoy DIY projects, making your own trench lighter is a fun and rewarding challenge. One popular method involves using an empty bullet casing as the body. By cutting off the end and threading a specially treated cotton rope through it, you can create a functional and rugged fire starter.
Forum user Jay Valencia shared a detailed guide on building his version, called a “chucknuck.†He experimented with various materials before settling on 100% cotton rope, which holds an ember better than other types. His design doesn’t include a spark wheel or a steel ball for snuffing the ember, but instead uses a simple method — holding the lighter upside down on a flat surface to cut off the oxygen supply.
Jay also warned about common mistakes, such as cutting too close to the extractor groove of the bullet casing, which could damage the primer well. He emphasized the importance of choosing the right rope and being careful with the construction process.
Whether you buy one or build your own, the trench lighter is a unique and useful tool that has stood the test of time. If you're into bushcraft, survival, or just enjoy tinkering, giving it a try might be a great way to expand your skills.
