Tool Logic Fire Folding Knives SL3 are portable, lightweight folding knives that could mean the difference between a roaring fire and a cold night in the dark. This Tool Logic knife has at its heart a 3" stainless steel blade with a partially serrated edge. The blade moves smoothly in and out of the black handle with a rounded thumb notch, and the back edge of the knife has thumb grooves for improved leverage. Tool Logic Fire really shines when at the campsite or in the woods, where it's most useful as a fire starter. Tool Logic has built a removable magnesium alloy firestarter into the handle of the SL3 Fire, which, when struck across the knife, produces a shower of sparks hot enough to ignite tinder and kindling. These knives also feature an extra-loud emergency whistle, great for flagging down rescue vehicles and calling for help. Weighing just 3 ounces and measuring out to only four inches when folded, the SL3 Fire Knife is incredibly easy to carry anywhere, an important trait for essential survival tools like these. For a folding knife that can keep you warm in the right circumstances, equip the Tool Logic SL3 Fire Knife.
