Is there a way to lock in a patina, so it stays where it is without advancing further? Or even preventing one from starting st all? For reference I am curious in regards to a 1095 carbon blade and a brass flashlight I own. (I'd post a pic if I didn't have to use a hosting service)

I've heard of fitz, never used it however.
 
"Patina" is basically oxidation.
Both 1095 steel and brass will oxidize unless air and moisture are kept from the surface.
Buy some Simichrome polish and use it on your items. Then, oil your knife blade. Wax your flashlight.
 
I patina almost all my carbon steel knives right out of the box by sticking g them into a tall glass of warm vinegar. Then I stop the process by running, then slathering them with dishwahing soap. The alkaline in the soap neutralizes the acid in the vinegar. After drying, I keep a thin coating of oil on the blade. This seems to stay pretty stable, even in the constant humidity of Florida.

For the flashlight, if you are serious about it not changing your best bet is probably a wiped on layer of clear lacquer. And or spray it on. Kind of futzy to keep up. Lacquer solvent is pretty poisonous so read up on it and use it outside with a respirator. Wax is pretty permeable to water; any good cabinet maker will tell you that. Body heat will soften it and so it will come off onto your bare hand or glove also leaving the metal even more vulnerable.

I say lacquer because it is easily recoated because the second layer will partially dissolve the first and the layer will bond. Other clear coatings not so much or not at all. Just look at all these cars driving around with clear coats that look like sunburned skin pealing. Those are NOT lacquer they are basically plastic / epoxy clear coat and they take some serious work to fix.
 
To prevent patina, wipe down your item with Tuff-glide. You'll never see patina on it.
