California-based survival brand Tortoise Gear has created a crafty add-on implement for your Victorinox Swiss Army knife. The FireAnt twists onto the knife’s seldom-used corkscrew, adding the fire-starting capability of a ferro fire-steel plus waterproof, melt-proof waxed cotton Helix tinder. It adds no additional bulk to the knife and lights up like a charm in any weather. A funded Kickstarter.
