Tools for engraving/scrolling

Hello everyone, I am new to this forum here.  I have a question for you all.  I am interested in building a custom stock for a rifle of mine from scratch.  I would like to do some checkering and perhaps some engraving on it, and I am curious where I should start with this.  What kind of tools are used to do this, and where can they be obtained.  I am also interested in learning to do some scroll work on metal.  I know both of these take many hours of practice to get any good at, and I am willing to put in this time, but I don't know what tools to use for it.  Thanks for any help,
