Tactical Sharpies are a perfect addition to your edc gear. The sharpie is gutted out and replaced with a G10 rod that obtains a sharpened point.
The G10 Tactical Sharpies will pass a metal detector with no issue, as it contains no metal. Perfect for all those non permissive environments.

G-10 is a high-pressure fiberglass laminate, a type of composite material. It is created by stacking multiple layers of glass cloth, soaked in epoxy resin, and by compressing the resulting material under heat until the epoxy cures.
