German Longsword Study Guide
This book compiles the research into the subject of the Liechtenauer tradition (and its outliers) from the past three years. It is an excellent study guide for people who have learned the system from their instructors and who would like to put their knowledge into the context of the historical sources. Students with advanced skill sets and assistant instructors will find this book particularly valuable.
