Just to help clear things up a bit - yes, these days, ALL product output by USPC is traditionally cut.
There's a simple and almost humorous reason as to why.
For some reason, making cards traditionally cut involved taking the paper as it comes out of the printer and flipping it before it's put into the machines that cut sheets into strips and punches cards out of those strips. For the sake of efficiency, at some point in the 1980s, USPC stopped making traditionally cut decks, eliminating this flipping-over step - you had to specially request it, pay extra for it, and they were generally not too thrilled about doing it, from what I've heard.
When they opened the new plant in 2009, they had new machines to work with - and around the same time, some adjustments were made to the thickness of the paper as well as the percentage of post-consumer recycled content. As they started working with these new machines and the new stock, they started running into jamming problems with the new cutting hardware. Someone on the factory floor discovered that if they went back to the old way of flipping the sheets over, they jammed less often! So now, lo and behold, all USPC decks are traditionally cut!
I learned about this during one of the 52+J conventions - we had a convention in Erlanger, Kentucky a few years back, which included a tour of the factory floor as well as a Q&A session and some free swag. The most notable item they gave us was the Norwood uncut - an uncut sheet that was never intended to be cut into a deck in the first place. On the faces, it has USPC standard faces with one joker each from Bicycle, Bee, Aviator and Hoyle, and a Bicycle Ace of Spades. On the back, there's a sheet-sized collage of photos taken in the Norwood section of Cincinnati - various signs, buildings, etc. It's one of my wife's favorite uncut sheets out of my collection.
