TuffWriter pens were designed to withstand high levels of abuse should they be pressed into the role of a self defense tool. They are 100% made in the USA and constructed using state of the art machining and aerospace grade materials. The market has become flooded with so called "tactical pens". However, it takes more than cramming an ink cartridge into a metal tube for a pen to truly be considered a serious tool. Such things as: -Thick walled construction of either aircraft grade aluminum or titanium. -Strong spring steel clip that is both chemically and mechanically attached to ensure the pen stays put. -Optimum thread pitch on all components to ensure pen will still function even after delivering hard strikes. -Superior finishes such as a true hardcoat anodize, Robar NP3 coating, etc. Compare the construction and attention to detail on a TuffWriter pen to any of the offshore pens, and you will clearly see the differences that make a TuffWriter pen a true hard use device.
