My first book was "The $50 Knife Shop" great book but definitely not as deep into Heat treating as it seems you want to go! As far as steels however any 10XX Steels should serve you well!! 1075, 1080 and 1084 are fantastic steels for all makers, new or experienced (stay away from 1095 for now)!! As others have said especially being relatively new to this stay with known steels as they do increase your chance of success! I will modify my last statement with do use mystery steel for practice! It's great for messing around and trying ideas out without using your known steels. All that said ask questions, there are many well known makers here that are a wealth of knowledge and aren't afraid to pass it on!
