Firefly adds firepower to your Swiss Army knife! Firefly is a firesteel flint type fire starter tool accessory replacement for the Swiss Army knife toothpick. Designed and manufactured by Tortoise Gear for use in Victorinox brand knives. Regular size Firefly replaces 50mm slanted top toothpicks for use in Victorinox knives 84mm and larger. The Firefly is made from a superior custom ferrocerium misch-metal formula giving it many advantages. The softer custom metals mix provides greater flexibility making it less brittle and giving it double the break strength of a typical firesteel or ferrocerium formula. The softer metals formula also allows for bigger sparks without harming the relatively soft stainless steel metal tools of Swiss Army knives. The Firefly mix sparks very easily with very little pressure needed during the strike. Every Firefly comes with a glow-in-the-dark top. When charged in sunlight this provides up to 12 hours of glow to help find your knife or Firefly at night. Two color choices are available: Neon green-yellow glow, and classic ivory glow. Firefly products come in high quality packaging with fully illustrated instructions for use printed on the inside. The re-closable clam shell can be used to store removed toothpicks and extra Fireflys. Firefly products are backed by a 1 month manufacturer warranty against any manufacturing defects.
