Description: The QSP Penguin is probably the best EDC knife you can get for the money. The blade is made of D2 tool steel, and has a sheepsfoot blade shape with a straight edge. The handle is made of brass that has a satisfying weight to it and is very sturdy. The deep carry pocket clip loops over and screws in behind the scale, making the knife slide in and out of pockets easily. The Penguin opens using the dual thumb studs and the copper washers.
