The Chaves Bolt Action Pen is machined from solid titanium with nice contouring for your fingers promoting ergonomic use. The Schmidt easyFLOW 9000 M cartridge writes extremely smoothly and deploys with ease. You may smirk but it's not always the case and we're glad to see it here. The Chaves Bolt Action Pen has an extremely solid feel - like it can handle absolutely anything and still sign a beautiful signature. It features Ramon's trademark titanium skull pocket clip that is one if not the coolest in the business and was proudly made in China by Reate Knives.
