The Hinderer Knives Investigator Modular Pen with Black Ink is crafted from CNC machined O1 Tool Steel and given a Black Parkerized finish, a phosphating coating for corrosion resistance. This finish is durable and has a tumbled look that wears well over time.
Robust and overbuilt to take a beating…and give one. The Investigator was designed to be as small as a standard size refill would allow, yet useful in tough situations. Uses Fisher Space Pen full size refills (pn# SPR4B).
Brand new direct from Hinderer Knives.
