The main purpose of this study is to compare various sizes of an extendible baton with the standard issue PVC duty baton.

This project also included a side handle baton and a traditional wooden duty baton.

Comparison was made on those quantifiable mechanical variables that were deemed significant with respect to trauma and the intended use of the baton as an intermediate weapon. These variables included impact force, impact pressure and movement kinematics while performing striking swings with these police batons.

Including graphs and illustrations for easy understanding.
