A square screw is a Robinson, fyi.

There’s some anti-Canadian bias in this chart for sure.

Don’t call Philips after the inventor but Robertson after the shape.

It’s less bias and more poor advertising awareness in the US and the rest of the world. Still, it does not diminish the simple effectiveness of the design.
“No! The RED-handled Robbie screwdriver! And hold the light steady” is like half my experiences with my dad. :-D Such a red-foreman.

Also the 6 lobe or whatever it’s called in the diagram is usually called a torx.

Robinson ftw though.

Robertson
Hahaha. Thanks, I didn’t even notice. Damn autocorrect.
in america everything must be named after a company
