Double bladed, my only gripe is the blade's a tad short. Most manufacturers of great knives don't want to go through the trouble sharpening both edges, but SOG. The characteristics of this knife make it a good fighting knife, but a little on the smallish side. Take a look at the Cold Steel Voyager with a 5- or 6-inch blade for not a whole lot more money. Chances are you'll drop this one in a heartbeat.
