Query: Not for the serious student of fencing.

The reality challenged will love this book. But, in truth, John Clement's self-important volume is not for anyone serious about reality. It is primarily for self-taught "swordsmen," those individuals who like to dress up in historical costumes and pretend they really know something about fighting with swords. Mr. Clements comes across with a certain arrogance, as someone who believes he has a monopoly on genuine sword fighting skills and knowledge. Be wary of those who pat themselves on the back. As a fencing master of some years, I do not recommend Mr. Clement's book except as a novelty.
