One of the original advantages of the Phillips screw was
that the wedged cruciform shape would cam out under
high torque, which helped achieved the proper torque in
early automated manufacturing. Today, torque feedback
accomplishes this in modern machines, but we're still left
with camming
screws that are a pain to use with hand
tools.
Many Phillips screws today feature both a Phillips
indentation in the center and a standard slot going through
the whole head, making it possible to use either a Phillips
or a standard slotted screwdriver with the same screw.
The Phillips screwdriver self-centers, but it cams out. The
standard screwdriver supports a higher torque without
camming out, but it slides off-center.
In the prior art, Torx and square screws are well-baked,
but they're not as common as the Phillips, unfortunately.
Proposed is a screwdriver specifically designed for
combination Phillips/standard screws. It would feature a
Phillips cross in the center with two longer wings to catch
the standard slot. It would only support two orientations
instead of the four supported by a standard Phillips, but
the additional torque before cam-out would be well worth
the extra precision, and the self-centering capability
would be worth the advantage over a standard
screwdriver.

The problem with this is that it would be useless for
either regular Phillips or regular slot-head screws,
which still make up the majority of screws. Useful if
you use a lot of the twin-mode screws, I guess, but I
wouldn't buy one - I spend enough time cursing as it
is. |

I was hoping this would be a screw with the Phillips cross not centered over the shaft of the screw, but off to the side. |

Angels have wings, and now so do screwdrivers. |
|
| |
Since it is baked, now is the time to film the late night tool commercial featuring screwdrivers with wings. |
|

And this wouldn't make the Posidriv faction happy |

I sit next to someone called Philip, and am now planning a sequence of events, ruses and setups that will give me the excuse to say something along the lines of "No, that's not Philip's screwdriver, it's mine." |

(N.B. This may however simply be an instance of procrastination taken to an extreme.) |

That can be solved relatively simply by purchasing lots of torx screws and leaving them around the house. |
