Your Weapon is a Tool
Scientific Principles for Powerful Staff Techniques
"Give me a place to stand, and I shall move the Earth with it" –Archimedes
The fundamental principle behind all Staff/spear techniques is the lever. A lever is a machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum. A lever amplifies an input force to provide a greater output force, which is said to provide leverage. The ratio of the output force to the input force is the ideal mechanical advantage of the lever.
When I teach weapons techniques even the smallest details are of importance. The reason I usually give my students is simple and colorful. I usually tell them that when fighting with weapons the person who makes the even the smallest mistake can end up dead. This is a truth of fighting with weapons and serves to inspire them to pay attention to the details. However, another important reason to pay attention to the structural details of weapons techniques is to gain the mechanical advantages of the lever principles. In order to get the maximum effect you should know where the resistance is, where the fulcrum is and where to apply the effort. Below is a video of me demonstrating staff/spear techniques, in each technique you can see the principles of one of the three classes of levers applied.
