Love your videos! New subscriber, FWIW.
I do have one objection; @14:20 you say you can’t use a flat-head screwdriver to drive a Robertson screw. As a Canadian AND long-time advocate of the Robertson form, you certainly can; just need to find the right size flat screwdriver to fit the diagonal. And all the benefits of the Robertson still apply: one-handed operation, higher torque, resistance to cam-out, etc.
Robertson-adjacent is the story I heard about why McDonalds uses (useta?) a triangular screw for their toys. Like a Robertson with 1 less corner. My colleague said McDonalds avoided the license fee price built into the other forms. My argument is there’s no way McD’s wouldn’t use a cheap knock-off Phillips in the Chinese/etc. factories. We never resolved it, and we’ve lost touch. Sigh…
Colleague was a fairly open racist, so it just seemed too “ching-chong-bing-bong” cringey to be right.
