The Sparky carabiner is made of heat-forged aluminum, making it strong so you can securely carry your keys and more. Just inside the gate is a bottle opener so you can easily celebrate life's wins. But what really sets this carabiner apart is the large, embedded ferro rod in Sparky. Marry Sparky with Scratch Key's hardened striker plate and now you're set to throw some great big ole sparks to light a camp stove, a grill, some tinder for the fire, etc.
