It's amazing how many companies out there that specialize in one thing and do that one thing very well.

Wow, what a cool company! Makes me itch to order hundreds of feet of ball chain and make a huge chain fountain [1] to entertain the kids!

When I was buying a bunch of N95 masks I came across "Bona Fide Masks" and was initially taken aback that it was the same company as "ballchain.com". My first thought was "Oh great, some shady thing...".

Then I got looking into ballchain.com and was quite impressed for exactly what you say: they do something really well.

This company restores dash boards for cars (anything from ~1960–~2000):

There’s a company specializing in restoring lighted panels for aircraft: https://aircapitoldial.com/

I’ve got a few friends/acquaintances running nice single-digit million revenue companies doing some of the strangest things.

One of them turned a quite niche idea (“ice as a service”) into a successful 8-figures ARR company and sold it.

Sweet! You get free shipping if you order 2000ft of ball chain.
