This ultralight fire kit weighs in at just over 3oz and is sealed tight in our new branded 6061 thick walled aluminum cases! Not only is it waterproofed from a protected o-ring seal, but it also contains the last striker you’ll ever truly need, The Spark Gauge Striker. Giving you the option to use more or less of your ferrocerium rod on each strike. The striker has been beveled to give truly amazing firing starting potential sparks and ground to be fully ambidextrous. It stands above the crowd as you can choose to release more or less sparks off your ferro rod by facing the striker on the unmarked, or Maker’s Marked, side. When the back of the striker faces you, you will throw sparks, but just enough for fire tinder, when you face the side with the Old Growth Artisans logo facing you, you will be throwing more than enough sparks to ignite almost any tinder in even the worst of conditions! Fully intended for use with all of our fire tinders, and includes one Ultralight Refill Kit.
