Tiny Footprint. Massive Firepower.
The Firefly Heat is a high-performance, ultra-compact fire starter tool designed for everyday carry. Crafted from durable high carbon steel, this rugged survival tool measures just 0.5" x 3.25"—small enough to disappear into your pocket, keychain, or pack, but powerful enough to spark a fire when it matters most.
Wrapped in a glow-in-the-dark silicone handle for grip and visibility, the Firefly Heat conceals a hidden ferrocerium rod inside, giving you a complete, always-ready fire tool that takes up virtually no space.

Why Choose The Heat Fire Starter Keychain?
Whether you’re a minimalist backpacker, an EDC enthusiast, or building out your bugout bag, the Firefly Heat gives you the peace of mind that comes from carrying a reliable fire starter keychain—without bulk. It’s discreet, dependable, and purpose-built to make fire-starting easy, even in challenging conditions.

Q: What’s the Firefly Heat made of?
A: The tool is made from high carbon steel for strength and spark production, with a ferro rod embedded under a glow-in-the-dark silicone grip.
