🌟 Why This Design
This idea comes from a real struggle I often face: I need tools with me, but I don’t always want to carry a full set. That’s where this design comes in handy. It gives me a minimal tool that fits in my pocket or on a lanyard, ready whenever I need to fix something.
Since keys are something we all carry every day, turning a simple key shape into a functional tool just made sense. This design upgrades a daily necessity into a reliable EDC companion — minimalist, practical, and smart, exactly what modern carry gear should be.
