Not sure of actual dimensional differences, but they are different.
Paul's was INFI, and the Ratchet/A2T is SR101.
The A2T is a version of the standard Rat Ratchet. A2T has the Resiprene handle, where the Paul's had the original "Satin Jack/Badger III/Public Defender" style micarta handle. There were some cord-wrapped Paul's offered at Blade a couple years ago, I think they were like $100 at the time.
I will try to get some side-by-side pics up in a bit.
