CRKT Pen is a tactical pen that is a little more stylish and looks like a standard ballpoint pen. However, the CRKT Pen is so simple that we don't think you can really call it a tactical pen for self-defense. Anyone who has had some basic training or understanding in using a pen to defend themselves may do it with ease. Additionally, they produce top-notch writing tools with black, blue, and many other ink options.https://www.lanierpens.com/CRKT_Pens_s/242.htm
