The NRA has a knife making class which is operated out of their gunsmithing school in Susanville, CA. It's about 90 miles NW of Reno. The school is pretty good and if you're a CA resident, fairly inexpensive ($33). You can also bring your rusty gun up there, sandblast or polish it and blue it or parkerize it during your lunch hour.
Absent visiting CA, go to a blackpowder sutler and he'll have all the raw materials and books. If you can't find a sutler, attend a black powder rendezvous in your area. You'll find a lot of guys make their own knives and they'll be happy to share their insights with you.
