Glad you like it. Unfortunately, there is no other instruction book available, but we are here to help with anything you are unsure of. The hat is a food holder for use with the square slicing inserts. The inserts are interchangeable, so you only use one at a time. The holder will poke the food and secure it and the inserts are for slicing, shredding or julienne cutting. When you slice using the food holder, you protect your thumb against further injury. Everything you cut will fall right into the bowl.
