Info from KnifeArt's website:
The exclusive GB (Gun Barrel) click pen provides a discreet way to carry a 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 provides several key features:
- Enhanced hand grip when in your palm - due to the flared end
- Weight reduced design - due to the 'gun barrel' style machined groves
- Reinforced barrel - due to the increased design thickness
- Superior writing traction - due the flared writing section that you grasp with your fingers - Thicker impact tip - due to the increased ti stock thickness at the tip
The GB click pen is constructed from aerospace grade titanium and is completed with a 6Al4V titanium clip. Titanium provides an extremely robust material while keeping the weight to a minimum. The GB gun barrel pen is 5 1/8" long. The GB weighs in a 1.1 oz (34 grams) as compared to the 1.0 oz (30 grams) of the standard 375 series titanium click. The GB click thickness is around .420" which is larger than MCM 375 series at .375".
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 while at the same time provide a positive grip. 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 titanium pen is of outstanding quality that you would expected of any MCM item.
The pen accepts Fisher Space Pen medium refills that are commonly available at office supply stores. We chose Fisher Space pen refills because Fisher Space PenÆs Sealed Pressurized Ink Cartridge performs in temperatures from -30 F to +250 F, underwater, in zero gravity, at any angleûeven upside down! The GB click uses a high-quality German-made ball bearing click mechanism. The Length of the pen is 5 1/4". Made in the USA by Matthew Martin Pens.
