United Cutlery silver defense pens are of high impact and great quality. These pens have a 6061 aluminum handle and are hard anodized so that they can withstand scratches. The overall length of the pen is 5-3/8 inch. The pen is sleek and beautiful in look and it writes neatly with blue ink color. The best thing is that, it is capless and has a handle thus can be easily clipped under any circumstances and we just have to twist the bottom and then the ball point emerges for us to write smooth. This pen can work as an ideal tactical defense tool and deliver powerful thrusts.
