GRIM WORKSHOP Firefly Heat: Ultra-Compact Fire Starter Keychain Tool

Firefly Heat: Pocket Fire, Anywhere

Ever tried lighting a fire when your “big” gear’s back at camp—or sitting in the glove box you swore you packed? The Firefly Heat is your backup plan’s backup plan: a palm-size ferro rod keychain fire starter with a high-carbon striker that throws molten sparks like it’s angry at the cold. The glow-in-the-dark silicone band doubles as a handle and a keeper, so you’re never fumbling in the dark for your only way to stay warm.

It’s small enough to vanish inside an Altoids tin, yet big enough to actually work when your fingers are freezing.
