This ultralight fire kit weighs in at less than 2oz and is sealed tight in an Ultimate Survival Technologies B.A.S.E case. Not only is it waterproof, but it also contains one of the most unique strikers available, “The Spark Gauge,” Striker. Giving you the option to use more or less of your ferrocerium rod on each strike. The striker has been angled to give good sparks and be fully ambidextrous whichever side you choose, but where it stands out is how you can choose to release more or less sparks at a time by facing the striker on the single, or double spark side. When the striker faces you with only one dot, you will throw sparks, but just enough for dry tinder, when you face the side with two dots towards your face, you will be throwing more sparks than your tinder can handle, so watch out as it bursts into flames! Fully intended for use with all of our fire tinder, and includes one Ultralight Refill Kit.
