How do i etch my damascus blades
 

I have dilute nitric acid but i need to know how to apply it etc will someone please advise.

Are these antique blades your trying to etch?

Yes they are

There's no simple answer Bally. Damascus is a 'wide term' and each type of blade requires different treatment. If you want the right guidance, then you need to be precise in your descriptions and show some pictures of the items.
Then you'll get more specific advice

I will post pictures 2moro.
