Grim Workshop Firefly Heat Firestarter Tool

Grim Workshop produce some excellent every day carry gear. They have all sorts of innovative ideas and cram them into dog tags, credit card or discs. The "Roundabout" series of tools are a really novel idea and a brilliant, compact way of carry some very useful tools.

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.

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.

How It Works

1. Grip the Tool – The glow-in-the-dark silicone handle improves grip and makes it easy to locate in the dark.
2. Slide the Wrap – Move the silicone sleeve aside to reveal the built-in ferro rod.
3. Strike and Ignite – Use the spine of the steel tool or another striker to scrape the ferro rod and ignite a shower of sparks.
4. Carry It Anywhere – Use the built-in hole to attach the Firefly Heat to your keys, zipper pulls, packs, or lanyards.
