TIP #2 - ALWAYS HAVE A TOOL HANDY
always, always have something easily and quickly accessible to
use as a weapon. Note that I did not say, "have a weapon accessible" which
is not always practical or advisable. If someone surprises you,
there should be something instantly accessible to aid in your defense. CBG
Safety sells a number of simple self-defense objects.
Anything you find that is hard and fast should be aimed at smashing against something
made of bone,
and anything with a point to it should be aimed at stabbing into soft tissue.
