I was just reading an article about Robertson screws. I didn't know they're uncommon outside of Canada. I also didn't know that they were on model T's. And I learned that ford wanted to license them but when Robertson, the inventor (and a Canadian), wouldn't, ford got screws from a man named Phillips.
Having learned all this and contemplating my past experiences with both I have reached this conclusion... I hate Phillips screws. If Robertson had licensed his screws to ford they would be dominant. I do wonder why they're supposedly a rarity outside of Canada, seeing as they are immeasurably better than slot or Phillips?
