Serrated Pen Knife

Works like a normal ball point pen, but conceals a knife for protection. The 2 inch knife is hidden in the tail end, which is easily removed for use. Half serrated and half straight, the blade can be used for cutting and also serves as a letter opener. Clip it to your pocket like any ordinary pen and when the need arises, just pull apart from the center to reveal the knife inside. Its camo finished stainless steel construction gives the pen a smart and sophisticated look.
