SOG Snarl Knife
More terrifying than functional — the SOG Snarl Knife combines the grip of a set of brass knuckles with a curving blade forming what could only be the creepiest-looking concealable weapon around. Measuring just over four inches in length, this blade is formed from stainless steel, and honed to a bevel with a razor's edge. Finger holes give you a firm grip and make it quick to pull out from its included hardened-nylon sheath (which you can carry on your belt or suspend from your neck). Regardless of how you carry it, it makes for a great last-ditch line of defense when you find yourself in a really tricky spot.
