Film is a very real possibility for you, especially with a 1K plate to do the heavy lifting. You could just do a 3 and 1um films and a piece of glass or marble tile. About 30 bucks for 20 sheets, 60 pieces you can do 4-600 razors. Less than 50 buck for your whole stone/honing setup.

Chrome Ox strop off a 1um film with a piece of paper is a very nice keen edge.
