Mark and Theresa broadcasted live from the Ironclad Technical Workwear forge at the National Hardware Show. We grind the gears with Popular Mechanic's outstanding, real deal editor Roy Berendsohn. And we cool the forge's fire with the metal-melting Cool Tools star and no first name necessary—Grundy. Then we hone our iron to a razor's edge with Marc Lyman, sharp-witted chief editor of HomeFixated.com. DIY Network's Cool Tools host Chris Grundy takes a break from hunting through the aisles at the Las Vegas Convention Center to talk with Mark and Theresa.
