In the latest addition to his Fighting Weapons series, Dwight McLemore does for the staff what he did earlier for the Bowie, tomahawk, and sword. The Fighting Staff is a modern illustrated guide to using one of man's oldest weapons. In keeping with his philosophy on fighting weapons, in this workbook McLemore does not attempt to duplicate methods from a specific period in the past. Rather, he offers an eclectic approach that borrows the most effective techniques from Asian and European martial arts throughout history. The Fighting Staff covers such essentials as footwork, grip, strikes, thrusts, blocks, and targeting. But its real value lies in the fighting concepts imparted, which serve as a language for advanced training. As always, your martial arts training is greatly enhanced by McLemore's beautifully executed drawings that take you step-by-step through 25 fighting drills for the martial arts staff. His use of frontal, side and overhead views, as well as his unique"floating staff" perspective, allows you to truly see how your actions correlate with those of your training partner (or opponent), as well as how and where your weapon moves.
The training techniques taught in this book are not limited to the staff. They can also be used effectively with other weapons. About the Author Dwight C. McLemore is a retired combat arms officer with the U.S. Army and is an accomplished bladesman and instructor. He is renowned for his vast knowledge of Bowie and big-knife fighting and has more than 18 years of experience in self-defense and martial arts. The founder of the School of Two Swords, McLemore is rated expert level with the American Knife Congress, is certified in kung fu, and holds 1st dan in kendo.

Harry Potter and the Sorcerer's Stone: The Illustrated Edition (Harry Potter, Book 1)
For the first time, J.K. Rowling's beloved Harry Potter books will be presented in lavishly illustrated full-color editions. Kate Greenaway-award-winning artist Jim Kay has created over 100 stunning illustrations, making this deluxe format a perfect gift as much for a child being introduced to the series, as for the dedicated fan.
Harry Potter has never been the star of a Quidditch team, scoring points while riding a broom far above the ground. He knows no spells, has never helped to hatch a dragon, and has never worn a cloak of invisibility.
All he knows is a miserable life with the Dursleys, his horrible aunt and uncle, and their abominable son, Dudley -- a great big swollen spoiled bully. Harry's room is a tiny closet at the foot of the stairs, and he hasn't had a birthday party in eleven years.
But all that is about to change when a mysterious letter arrives by owl messenger: a letter with an invitation to an incredible place that Harry -- and anyone who reads about him -- will find unforgettable.
