About Zirconium (Zr)
The GB click pen is constructed from rare and expensive zirconium metal. The zirconium is machined and finished by heat flaming to a dark black finish. Zirconium, while similar to titanium, provides an extremely hard corrosion resistant material. Zirconium is also significantly heavier than Titanium. Zirconium is known as an extremely hypo-allergenic metal. Zirconium is being adopted as semi-precious jewelry metal and once heat treated has an onyx-like hard black finish. Zirconium's properties also make it an excellent choice in the surgical instrument and biomedical engineering fields.
The GB pen is 5 1/8" long. The GB Zirconium weighs in a 1.6 oz (46 grams) where as the same pen in titanium is 1.1 oz. The GB click thickness is around .420" which is larger than Martin's 375 series at .375". As far as we know, Martin is one of the only pen makers in the world using zirconium (Zr).
The GB pen is perfectly sized and at the same time offers an amazing firm grip in case you are in a close-quarters situation in which you need to protect yourself. The gun barrel style grooves down the body of the pen reduce weight and provide grip at the same time. The pen took a considerable amount of machine time to create and is make of three separate parts.
The use of CNC and CAD_CAM technology that is state of the art to design and manufacture these pens. This pen is of outstanding quality that you would expected of any MCM item.

I first saw this pen on Knife Art while actually looking for another pen. This GB pen got my attention by the nice curvature in the grip area and the fact that it was made out of zirconium. I thought the price was a little high but decided to purchase it since it looked well built. Shipping was extremely fast and when I received it my first impression was WOW! It looks so much nicer in person. I then proceeded to try out the functionality of the pen. The clicky mechanism is really smooth and doesn't actually make a clicking sound. The pen feels comfortable and writes smoothly. The pen comes with O-rings that you can install at the bottom grip area. It feels nice without the O-rings but wanted to see how it felt with them installed. The O-rings provided were a little too bulky in my opinion but purchased a small variety pack at my local auto parts store that were thinner and smaller which makes a big improvement. If your thinking of purchasing a nice pen within this price point I would highly recommend this GB pen. I will have a more detailed video review online soon for anyone truly interested in this pen.
