I wonder why a square bead. Now I'll be thinking about that all night.
It used to be called a "Sourdough bead." The top of a round bead can seem distorted if the light hits it from the side, but the Sourdough's flat top doesn't. It works best if you match it with a peep sight.
Sadly, it's like pulling teeth to find one these days.
