Someone please explain why almost all the Coticule I have seen posted in the classified section here and on other websites share a unique shape? I think it is a rather handsome shape, if one could be so bold as to describe a piece of stone in such a manner.
If someone were to twist my arm and force me to make a SWAG (Sophisticated Wild A$$ed Guess) about the design, I would tell him it would soley for ergonomics, so the honer is at ease while putting the final stone touches on his razor. That being said, sure as I'm sittin' here on this hot summer night, someone will reply before tomorrow night letting me know that my SWAG was so far off base it was out of the park. And when he stops acting like my little friend to the left is doing, he'll let me off the hook and tell me why the coticule stones have the peculiar 5-sided design.

Thank you for the help. I know I can rely on my fellow gentlemen shavers to bail me out.
Smooth shaving to you all this week.
