I like Wayne Goddard's new book The Wonder of knifemaking he covers heat treat, steels eguipment, grinding, friction folder how to. I also like the Loveless book and Jim Hirsoulas The Complete Bladesmith I haven't gotten his others yet. I found a Book by Tim McReight and one by David Boye in my library system. I've found all of these helpful. BIG TIP.Do not loan out your books, they don't come back. I now offer to photocopy a section to share with someone, saves a lot of grief.
