What is this grind called? Channel Cut

[mr_houston]

Can someone tell me what this grind is called? It’s like a channel cut into a wedge.

This is a Joseph Haywood & Company razor. I like the grind.

Colloquially known as a blood gutter... The correct term is Fuller groove

There were some old Sheffields with similar grinds that were called 'Swaged', but that term was used on blades without the groove too.
