The $50 Knife shop by Wayne Goddard is what got me started.
"How To Make Knives" by Bob Loveless and Richard Barney is a good book, but I believe that some of the information (and the supplies he tells you to use) is kinda dated and there are better methods and supplies now. Theres a section with Bill Moran that is pretty good, but not extensive enough. The book sometimes isnt really extensive or simple enough for me. "Now to shape the handle we're gonna use the clausen vertical milling machine. Every knifemaker should have one." uh...okay?:jerkit:
David Boye's book has some great stuff in it, but is also very dated, and I believe some of his methods to be sloppy and uneccessary.
I'd stick with Wayne Goddard's books, and the tutorials and advice given here on the forums.
