The SureFire Pen II

Sure, regular pens are fine, but if you need a writing tool that can stand up to the toughest you have to offer, check out the The SureFire Pen II ($90). A more streamlined version of the original, the SureFire II features a hard anodized aerospace-grade aluminum body with nearly-unbreakable pocket clip, a Schmidt Technology easyFLOW 9000 ink cartridge with retractable action, a nickel-plated pushbutton tailcap, and more.
