Description: The Boker Plus Redox Pen from Boker Defense Pens is a mashup of centuries-old writing technology and modern engineering. The pen uses a unique metal alloy that works like a pen but never seems to run out of ink. This rare alloy, originally discovered in ancient Rome, became a favorite of some of the greatest minds in history, like Leonardo da Vinci and Albrecht Durer. In modern times, this special special alloy has been perfected and is now available worldwide! It has the writing texture of graphite and writes like a pencil. It's also permanent like a pen, but doesn't smear like one. Best of all, it won't write on your clothing, your hands, or anything but paper. Boker Knives have been around for many moons. They are durable and get the job done. Find your new Boker knife at Blade HQ today!
