Hot Shot Micro Tool: Keychain Ferro Rod Firestarter

Each Micro Tool is made to perform in the field, not just look good on a keychain. Crafted from stainless steel, they’re durable enough to use repeatedly without bending or breaking. Whether stored in a Micro Tool Tin, worn on a keychain, or stacked in a Micro Tool Silencer, these ultra-compact tools are built to handle the same challenges as full-sized gear.

They’re tough enough for the task, yet small enough to disappear until you need them.

Many Micro Tools are designed with Grim Workshop’s Original Reusable Tool Retention System, allowing tools to be removed, used, and returned to their backing for storage. This system ensures every micro multi tool stays organized and reusable—so your keychain tools last a lifetime instead of being one-and-done.

Grim Workshop Micro Tools are designed to outlast the situations they’re built for. Each one is crafted from durable materials, chosen because they can handle real use without bending, rusting, or snapping. These are functional, field-ready micro tools made for everyday carry, emergency use, and survival alike.

We know that when you reach for a tool in the field, it has to work the first time, every time. That’s why every micro multi tool we make is backed by Grim Workshop’s Lifetime Guarantee. If a tool ever breaks under normal use, we’ll replace it. Simple as that.

This guarantee isn’t just about confidence, it’s about trust. We’re a small, family-owned American company, and we stand behind every product that leaves our shop. Each Micro Tool represents years of experience designing EDC keychain tools that combine compactness with true function. However you carry it, you can count on it. When gear this small can make a big difference, it should be built to last a lifetime—and ours are.
