Every once in a while there comes along a great invention.
The “Robbie”, aka the square-drive screw, is one of these inventions.
Because the inventor was unwilling to give up control of his product during negotiations in the early days of the automotive industry, the Robertson never caught on in the U.S.A.
I’ve heard they have started making an appearance, but the Phillips is still the defacto standard.
There are many things that can be debated in this world, but this is not one of them. The Robertson is undeniably the best (for many reasons) and anyone who insists on using the Phillips (or God forbid a slotted screw) is just being stubborn.
Other than aesthetics (for a light switch cover, for example) I challenge anyone to give me one good reason why the Robbie is not superior to the Phillips or the slot-head screw.
