Hidden inside the pen’s tail are two mechanisms. First, there’s a twist lock that prevents the blade from accidentally deploying in your pocket unintentionally. Second, the titanium pocket clip doubles as the actuator for the blade’s OTF mechanism.

For those paying attention, yes, this is an automatic knife. Push the pocket clip toward the tail, and the blade springs forth. The same mechanism retracts it.

The pen is mightier

While its retractable blade might be enough to attract some attention, it’s far from the only thing this pen has going for it. Even without the blade, this is a solid everyday carry writing utensil.

The pen’s body is machined aluminum, offering strength and lightness. Furthermore, it measures 5.875 inches, making it long enough for comfortable usage — even in larger hands — but short enough for pocket carry.
