Balisong Pen

thingiverse

This unique item doubles as a butterfly knife and pen. Pins held in place by miniature nails give it a distinct feel, while heavy metal pieces with truncated heads secure balance in the handle. At the core is a standard PC screw keeping a specially seated Pilot G-2 07 ballpoint pen firmly centered. Such a pen showcases impressive agility and allows users to demonstrate advanced techniques that can impress friends. Superglue might be necessary for assembly or customization adjustments.
