Today is Book Bomb Day for James Rawles' latest book Tools for Survival. We received an advanced copy and I can attest how useful this volume is.
The layout is clever. Mr. Rawles takes a variety of survivalist subjects (i.e. food preservation, tools and tool making, knives, medical tools, wood tools, firearms, etc.) and examines the various tool options on the market, their merit, and the good and bad about each item.
I consider this a highly useful addition to any prepper's library...
...but as with any such addition, its greatest usefulness comes from acting upon the knowledge contained within.
