Building off of the popular Extreme Duty Pen, Rick Hinderer listened to his customers who also desired a smaller, "easier to carry" Heavy Duty Tactical Pen that could still get the job done...and so the Investigator was born. 
From the deep grooves that run perpendicular to the length of the pen body to the deep cut threads of the cap and the bullet (which is Modular and can be customized with other accessories), this pen is sure to hold up to the toughest situations and strikes. 
You will feel the overall toughness and quality of this pen as soon as you grip it.


  • Designed and manufactured using state of the art CNC and CAD_CAM technology.
  • “Overbuilt” toughness designed to withstand all sorts of punishment
  • Course threads used throughout for extra thread height which translates into a very strong tough thread able to take the punishment of everyday hard use.
  • Modular design so the user may add a multitude of end attachments to configure the pen however the customer desires.
