GRIM WORKSHOP Firefly Blade: Credit Card Knife for Your Wallet

Firefly Blade: The Credit Card Knife with Built-In Firestarter

The Firefly Blade is a true credit card knife designed to live in your wallet while still delivering real cutting and fire-starting capability. Made from high carbon steel and sized exactly like a credit card, this wallet knife combines a sharp usable blade with an integrated ferrocerium rod, giving you both cutting and ignition in a flat, everyday carry format.

This credit card knife is built for people who want real function without bulk. It fits in a wallet, pocket organizer, or compact survival kit and stays with you when full-size knives cannot. Whether you are building a minimalist EDC setup, an urban survival kit, or a discreet backup blade, the Firefly Blade turns unused wallet space into practical capability.
