The Merrill Knife Book is an excellent book on the color changing knives. It includes many clear B&W photos throughout. They show both performer’s view of the hands as well as a mirror view to show what the spectator would be seeing. The writing style is very instructional. I personally find some sections a bit irritating with sentences such as, “Try it again without the knife in your hand. Try it again. Now you are getting the hang of it! This is what I am writing about…You were a bit clumsy that time! Try it again. You are trying to move your wrist too much” (page 34). Also, certain paragraphs are written in all capitals, which in the electronic correspondence world relates to being yelled at. Despite these minor points, however, the lessons are good and the explanations are very thorough. You will learn the normal move, the push through change, the twirling change, the snap change, learn some routines, a couple of switches, and read good advice on presentation. An essential guide to the color changing knives.
