There is no joint on an all-in-one, because the flight and shaft are moulded as a single piece. That removes the thing that interrupts more legs than anything else — a flight working loose, rotating, or popping out when the next dart strikes it.

It also fixes the flight angle permanently. A pushed-in flight seats slightly differently every time it is replaced, where a moulded unit is identical from the first throw to the last.

Worth knowing the length quoted refers to the shaft section rather than the assembled piece, so overall these sit in the same range as a conventional short shaft with a flight fitted. Target's K-Flex, Mission's Force 90, Winmau Fusion, Shot's Flight Deck and the Japanese Condor systems are all stocked, in standard and slim shapes.
