What is Reddit's opinion of Mastering Knife Skills: The Essential Guide to the Most Important Tools in Your Kitchen (with DVD)?

From 3.5 billion Reddit comments

I liked this book, a lot: http://www.amazon.com/Mastering-Knife-Skills-Essential-Important/dp/1584796677

Also, the CIA used to produce a knife skills book that is now out of print. If you find one in a bookshop or something, it has some good stuff in it.
