The second generation of the Commander C10 ballpoint pen features the following improvements 

• Slimmer size, better-looking design, and more comfortable grip
• The newly designed clip, CNC machined from titanium alloy
• More ergonomic bolt-action mechanism
• An additional German SCHMIDT P900M refill is included.

The Commander C10 Gen2 titanium bolt-action pen has a slim size - 124.8mm in length and 12mm in diameter (end), and weighs only 35g / 1.23oz. The entire body and clip are made of titanium, a high-quality, lightweight and durable material widely used in the aerospace and medical industries.

With a stonewashed and sandblasted finish, it's more resistant to wear and tear and won't get scratched in your pocket or even with your other EDC gear in your bag. 

The optimized bolt-action mechanism provides a better experience when advancing and retracting the refill. The bolt shape has also been redesigned to have textures on it to prevent slipping when advancing or retracting the refill. The German SCHMIDT P900M refill provides a smooth writing experience.

At the end of the pen is a ceramic ball that can be used as a glass breaker in an emergency. The C10 could be a tactical pen for self-defense.
