Imperial measurement system. Ffs just convert to the metric system already
Anyone tangentially studying anything scientific with real life measurements in the US is versed in metric. Imperial really is for the dum dums and their precious feel feels.
I just wish ibdidnt have to own 2 sets of tools. Even if we officially swap, im still going to have to keep 2 sets because of all the legacy junk around.

Fuck, I forgot about auto work.

Also, I think hex heads are more prone in smaller applications. Phillips should’ve been the square head.

Phillips was going to be the square head, but there pattent / licencing issues i think. Torx is my fav now, but i also understand that its expensive and complicated to manufacture, especially in the past.
I’m a torx lover after rebuilding my deck! Box of 500 comes with one bit and that’s all you need.
