Company History

ASP manufactures telescoping batons. An assessment by law enforcement officers found them preferred to the usual straight baton for their portability, convenience, effectiveness, usability, and psychological impact.
Since the early 1990s, ASP batons have been adopted by law enforcement agencies in the United States, United Kingdom, Canada, New Zealand and Australia. Expandable batons in general are sometimes referred to as "Asps".
The batons come in three sizes:, and, and the company has adopted a European measurement standard. They are available with several variations, such as color, grip pattern and material, and metal composition, the most common being 4140 high carbon steel, with an "airweight" line using a light-weight alloy with a combination of steel and aluminum.
ASP batons were friction-lock in design, and were opened by swinging the handle forcibly through the air. To close this type, the baton's tip is driven into a hard surface to break the friction. A version introduced in 2010 but since discontinued is called "LeverLoc", opened the same way was as friction-lock, but closable by twisting the shafts with both hands, and slightly longer when collapsed state due to the mechanism; a LeverLoc designed for plain-clothes concealment was also produced. The friction-lock Airweight series, for plain-clothed concealment, was released in 2012.
