Apparently works on bears as well...From the Site:
<span style="font-style: italic">Carrying a regular knife is useless against a bear or similar predator, but the WASP with its massive injection of compressed gas can have a devastating effect on mammals of any size</span>
you try and use a knife anything smaller than a house and you are just plain stupid. You wouldn't get close enough to a frickn' bear before it knocked your head off of your body.
