Riptide is the prized sword of Percy Jackson. Riptide draws its amazing power from the ocean, which is why it works only for children of Poseidon. In its dormant form it's a ballpoint pen, but once uncapped, it transforms into its true sword form. The pendant is silver-plated (blade) and gold-plated (hilt) zinc alloy and is 3 inches long. The pendant is on a 20-inch silver-plated chain with a 2-inch extension.
