Why is it when they hand-shuffle blackjack that there is a part where they turn one half of the cards around 180*?

To avoid players that are "edge sorting" Here is a link from a WOV member telliot.

I had an idea it had to do with something of that nature- and that it was a cheat-limiting move (or AP limiting move) but could not put my finger on exactly what.. after seeing how big an advantage that gives the player no wonder youd be tedious enough to look at those small edges- asuming you get your hands on the entire deck after a while.

Casinos that use auto-shufflers I never see them turn some of the cards before placing them in the shufflers or maybe they are doing it to all the ones shot out and just put the group in one way or the other every hand played? - I know some shufflers can read the cards and place them in order by a randomly chosen number but i dont think they actually turn any.

Take Pai Gow Poker for example. Players see and handle 7 cards each. If you and your 5 teammates take over a table, you probably turned them all after only two hands. OK, four hands because of the other deck in the shuffler.

They should. Many do.

Edge sorting is not as easy as some people make it sound. But, if you find a place where you can touch the cards and they don't turn before they shuffle, feel free to give it a shot.

Watch the slug more carefully. It's almost certainly done in any face-down machine shuffle game, and it's probably done in a face-up machine shuffle game, too.

If it's a pitched game, the pitch usually introduces a random turn to each card as it's dealt, too. For game security on pitched games, the dealer is usually supposed to keep the deck close to their body, held in a way that the card backs are not readily visible. Some places ask (require) that players be seated during pitch games, to further inhibit edge sorting.

Edge sorting isn't practical any time the deck backs are symmetrical and identical.
May the cards fall in your favor.
