This flash light also acts as a Mace. It is 17" long and comes with a spiked end (similar to a mace) and the very end is also sharp pointed. The flash light is great and is 500 lumens. It is Aluminum and comes with a rechargeable battery but also has a cartridge to put in AAA batteries so you can use that. Great item to keep in your car when you need a light or maybe just a little security.
