Do you know why manhole covers are round? Because a round cover can’t fall in the hole.



Mostly they are mass produced by the lowest bidder(or someone’s brother-in-law), and are all the same. That cuts costs and discourages “collectors”



But there are exceptions. Japan seems to be an exception.




Then there’s Germany which loves to over engineer stuff making it difficult and expensive to produce. Instead of having a man climb down a ladder they build it like a wine cellar… or a dungeon.
