John O'Callaghan, also known for OC Studios and OC Blades, is a custom knife maker and photographer based out of the San Diego area. He's a purebred New Yorker, where he worked as a crane rigger and mechanic to put himself through art school. Getting his start apprenticing for the Navy Seal run Half Face Blades, John quickly learned the craft of knife making and began creating blades in his own style soon after. In and out of the water, John can be caught with camera in hand shooting anything from ocean movement to street portraits of Hollywood's elite. A bit of a jack of all trades, John embodies the saying "be too complex to categorize."
