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 micarta that will patina over time, making each knife unique to its user. 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.
