Welcome to the addiction! I started out by reading everything I could get my hands on about knifemaking, in books, magazines, and on the internet. There are several different online forums available for knifemakers that are a wealth of information. Probably an even better introduction would be to find a knifemaker close to you and see if you can visit his shop and spend a little time learning the basics. Where are you in Texas? There might be somebody on this forum close to you, and I'd bet that someone here knows someone fairly close. Hope that helps.
