This heavy duty pen is made of 6061 T6 aircraft aluminum so it's virtually indestructible. Crafted by Schrade, the push button design is simple and familiar. The pen uses Schmidt 9000M Parker Style refill cartridges so you can be assured you'll always have an excellent writing instrument available for your use. It has a pocket clip so you can keep it close at hand for those times when signing with a ruggedly stylish pen is your best option.
