Last month I posted a bunch of Canadianisms including this one:
- Robertson-head screws. I had never seen them in the US. They are clearly superior to anything else, and why they haven't been adopted in the US is a big puzzle (and, no, please don't invoke network effects; the costs of change are minor relative to the benefits. Screwdriver bits are cheap.).
That paragraph in the posting prompted some discussion in the comments section.
Wouldn't you know it. Yesterday I was helping my son, Adam Smith Palmer (who lives in Texas), assemble a tumbling composter and sure as shootin', the screws included with the product were combination slot-Robertson screws. He had a couple of those neato screwdriver combos from Home Hardware in Canada, which include Robertson bits (of course) and made the job MUCH easier.
