ZEROHOUR APEX is a tactical pen for extreme conditions, designed with indestructible materials, an out-of-this-world waterproof ink cartridge, and tungsten steel glass-breaking tip. Apex's shredded for duty body puts some real muscle behind one of the smallest and strongest everyday carry tactical pens ever. A ZeroHour tactical pen has to be made with the best materials, which is why we returned to our cherished 6061 Aircraft Aluminum for the body and gave it a cool black matte finish. But we know that the ultimate material in luxury pens is titanium, so we added a beautifully polished Grade 5 titanium option as well.These materials, along with an ergonomic grip and balanced weight distribution, make APEX feel extremely smooth and light in the hand, while still giving your tactical pen nearly indestructible strength. The form of a pen is pretty much a given - tube, click or cap, ink reservoir - but APEX explodes the standard with a rugged, ventilated body that reveals the unique brass cartridge locked and loaded inside. APEX's brass ink cartridge is none other than the patented Fisher Space Pen refill (Medium Black PR4). Nitrogen-pressurized and sealed, with a tungsten carbide ball and stainless steel point, the Fisher cartridge can write in zero gravity, underwater, upside down, over wet and greasy paper, at any angle, and from -30 °F to 250 °F!We chose the Fisher Space Cartridge as our exclusive ink refill because it's simply the best and most reliable one ever made. NASA, armed forces, public safety, and outdoor enthusiasts depend on Fisher's durability, versatility, and thixotropic ink, which writes three times longer than an ordinary ballpoint. Whether you're indoors or out in the field, APEX is ready to engage in word battle or real battle. Deployed skillfully, APEX adds new truth to the old saying: the pen is mightier than the sword.
