That's a 13" round GI peel. Pulled to the edge, it will yield at best a 12" pie. Assuming those are 13" plates in that video, those are 12" pies. We've eaten there, and his pies are not 13". Don't get me wrong, I'm a 13" NP guy all the way, but you are not going to find many 13" NP pies in NYC or any of the big name places in the US for that matter, and a lot of them are smaller than 12".
