It doesn't provide any real details or anecdotes, which would make it more interesting. I like knowing that Adam Savage is a fan of Bill Harsey, CRK and Spartan. But I want to know what knife Hugh Downs is carrying. I'm guessing a Randall, from his time as a young(er) Vietnam War-correspondent. If he actually
was a Vietnam War-correspondent. And Judge Ito. Nice.
Here's one of those DDR Customs owned by Tyler. Or Perry. Or Tyler Perry.
