Heretic Thoth Pen Aluminum barrelThe Thoth is the first pen design from Heretic Knives. It features a stonewashed titanium tail cap, a stonewashed titanium end cap, a black anodized aluminum barrel, a blue anodized titanium bolt, and a stonewashed titanium rollerball clip. The pen is modular so you can run the pen full size (5. 02") or you can remove the barrel and ink cartridge extension to run a smaller version (3. 48") with no additional purchases required or tools.
