The Complete Modern Blacksmith
This is a great all around book. It focuses on making your own
tools from scrap or recycled materials. I love this book and it's
author's very professional drawings found throughout this book.
Not only does it focus on tools and making all kinds of things,
but the author get's into the correct way to hammer and how to
make your own lathe etc. This is a book that should be in
everyone's library. It is actually three books combined into one
book - what a deal!
