Having grown up in the shadow of the R&P factory and two parents who worked there, I was educated early on about the benefits of that particular driver and the screw-head configuration.
Do tell!

i even have a set of robertsons .any type can be used for scratching or gouging, but for proper finger piercing velocity you will require power tools ,i recommend makita 18 volt cordless drills
Get yourself a bit holder with a sleeve and use it faithfully. You won't regret it.My Ryobi 18 volt driver has given me "twin" power scars on the pad of my left thumb. Don't mind the pain too much, but the 6 weeks to heel up is annoying.
Henry F. Phillips (1890–1958) was a U.S. businessman from Portland, Oregon. The Phillips-head ("crosshead") screw and screwdriver are named after him.[1]
The importance of the crosshead screw design lies in its self-centering property, useful on automated production lines that use powered screwdrivers. Phillips' major contribution was in driving the crosshead concept forward to the point where it was adopted by screwmakers and automobile companies.
Back in IBM land, everything was straight slot. Never needed a cross-slot driver in the tool bag. Of course they made up for that with their fluted socket-head screws, commonly called Alien screws to distinguish them from Allen screws.
Used to confuse the new guys asking for a "negative" screwdriver, and then having to explain that there were negative and positive drivers for - or + slots![]()
Yes I have plenty of Phillips screwdrivers, that's how my Snap-on dealer put his kids through college.
