What type of comb does my Blue Frizzled Sizzle (satin) hen have?

[Happy Henny]

Hello,
I am wondering what type of comb my Blue Frizzled Satin hen has. All of it looks to be a walnut comb but at the very end of it looks like a prong from a single comb.? Any thoughts?

My silkie hens all have a similar comb to that, my silkie roosters I use to have started out with that kind of comb and over time it became a more pronounced walnut shape but with the hens I have it just stayed like that, I would call it a not pronounced walnut comb
