Police batons are carried both for self defense and riot control by police, correctional officers and military personnel. Police Batons can be used in both defensive and offensive postures. Common baton types are Friction Lock batons and Auto Lock batons. Friction lock batons have to be closed by hitting the baton tip on the ground in a downward motion. Recently Friction Lock and Talon batons are becoming more popular as they feature a push button closure.
