I was motivated to produce this collection for two main reasons. The first was Hapkido captured my interest and has held it through 10 years of training. I am analytical by nature and I tend to want to break things down into small pieces and look at each piece intently. I also enjoy putting things together to accomplish an end goal. This is also how the title of the book you hold in your hand came about, Toolbox Hapkido. I consider each self defense technique a tool that is available in your self defense toolbox. As we add techniques, we add tools. This gives you more options.
