Making Breakfast Sausage

What is the size of the cutting blades would be used in breakfast sausages, sausage and Cumberland sausage Lincolnshire?

Hmm, when I made the sausage, I never needed a cutting blade. I just throw the meat in the grinder plate mostly with smaller holes. Mix together and exchange on the mill fixation with the extruder and it's done.
You do not know where a cutting blade is at stake

it depends on what you prefer. I always use blades secondary
