Keeping all recipes after specialty switch?

[Blackfriday]

Was just wondering if anyone knows whether or not you keep all of your Blacksmithing recipes if you change specialties?

Do you lose the armorsmithing ones if you switch to weaponsmith?

etc,etc,etc.

I imagine you keep them, but you're just unable to craft it until you're the correct speciality again.

You lose the specialty recipes, but keep all regular ones.
