You Can Light a Fire With a Lighter, Even If It Is Broken.
It’s always a good idea to bring a cheap lighter with outdoor gear with you. Even if it runs out of fuel or breaks the plastic cover, it is still a great tool for starting a fire.
Whether your lighter is broken, or you just accidentally found one on the ground, YouTube Grant Thompson shows you how to start a fire with it in this video. Find a long, flat stick or surface and slowly roll the impact wheel of the lighter over it, holding the lighter sideways. Make sure you move slowly enough so that no arcing occurs and repeat the process 40 to 50 times. After a while, the lighter’s lid will be filled with ferrocerium powder. Just throw it on the kindling and light it with your lighter as usual.
