Riptide/Anaklusmos

Riptide, or Anaklusmos in Polytonic Greek, is currently the sword of Percy Jackson. It was originally Zoë Nightshade's hair pin and later in possession of Hercules, a Greek hero so he can fight the dragon Ladon. Anaklusmos is a sword made of celestial bronze, meaning it can only kill monsters and cannot harm mortals. It has been passed on for many generations, and luckily its current master is unlike Hercules. Riptide was made in the Cyclops' forges in Mount Etna and bathed in the River Lethe. Its form when not battling is usually a bronze ballpoint pen, the same exact pen centaur Chiron used to teach Greek games during Latin class in Yancy Academy.
