I've run into a problem with a blade I'm currently forging, that I'm hoping someone can help with.
My current project has a vine and leaf design chased/inlayed into the side of the blade(my terminology may be off). The problem I'm having is that I would like to inlay brass or copper into the pattern, but I don't know how to make it bond with the blade steel. If anyone can give me some advice on how to inlay the brass, I would love to hear it.

If it would help, I can take a picture of where I am at with the knife right now.
