"I designed this pen to be the ultimate field duty pen. It has all of the features that I look for in a tactical-grade pen: strength and complete functionality as a writing instrument. The GB Series features a 'gun barrel' style machined flutes to reduce weight yet the zirconium gives it a heft and strength that is unmatched."
The exclusive GB (Gun Barrel) click pen provides a discreet way to carry a ultra tough pen that offers both form and function. Matthew Martin has a knack for executing a precision instrument of the highest fit and finish.
The GB Click in Zirconium provides
- Enhanced hand grip when in your palm - due to the flared end
- Weight reduced design - due to the machined groves
- Reinforced tip/barrel - due to the increased design thickness
- Superior writing traction - due the flared writing section that you grasp with your fingers
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.
