Phoenix Rock Gym magnets. These magnets were given to the competitors in the Thrash & Dangle Fest climbing competitions. Originally the magnets were created by Chris Raypole with Climbing Dynamics, which the first generation of magnets had no words on them. Marty Karabin carved the letters into the magnets for the second generation of magnets. Will Haeberle then recarved the letters deeper into the magnets where the third generation perfected the final creation.
