Like most of the vendors in the Inventors Spotlight section of the 2010 National Hardware Show (NHS), Kalvin Vogt was confined to an 8-ft.-wide space that ran approximately 4 ft. deep. But he was right at the entrance with his crystal doorknobs, which are illuminated from inside with LED lights.


“We had Home Depot come in the first 15 minutes of the first day,” said Vogt, CEO of Krystal Touch of New York Inc. This being his first time at the show, Vogt and his associates were stunned. “We were ready to leave right after that,” he joked.
