While pens tend to have one sole function, the APEX Tactical Pen designed by ZeroHour entirely shattered this model by adding to writing the ability to be used as an underwater pen and even a self-defensive tool. The pen is engineered using high quality titanium metal making it a durable pen to rely on for multifunctional use.
The pen is designed out of Grade 5 titanium and aluminum that is used in the construction of airplanes. This allows the pen to be used emergency situations to shatter glass or even as a self-defence weapon. In addition, the ink can be used to write underwater should a situation arise where the consumer needs to do just that. Despite the durability and multipurpose engineering, the pen looks slim and sleek for everyday use.
