Flytanium Spyderco Paramilitary 2 and Para 3, 1194SB Stonewashed Titanium, Blue Tritium, Stopper

This Flytanium Stonewashed Titanium, Blue Tritium, Stopper is a cool spare part for your Spyderco Paramilitary 2 or Para 3. Make your knife entirely your own! What's special about this stopper is that it contains some tritium. Tritium is a mildly radioactive material. Don't worry though, it's completely safe! The radioactive energy results in light. That's why it's often used for expensive watches. The amount of light the tritium in the thumb stud gives off is comparable to that of watches. It's an elegant touch, and it makes it super easy to find your knife in the dark.
