always carry penknife but use it as a last resort.
get the larger size penknifes, the thicker ones.
if really kenna cornered by gang, then pull it out to ward them
off and run to the nearest help point.
nowadays kids very violent and sick.....will corner you, bash
you, video-tape it, strip you and post the vid on blogs and
youtube......since you offend them already, then must take
precautions.
those people who ask you not to carry penknife to defend
yourself....don't listen to them....because if things happen to
you, it's not their responsibility or business.....unless they can
post their real name and home address here to say they'll be
responsible for their advice.
What if u take out the penknife and the police come? What will u
be charge under?
