If all you have is a hammer, every problem looks like a nail.
If all you carry is a pistol, every incident looks like a shooting situation.
I carry a pistol where I can.
I carry 2 Spyderco Delicas, left and right.
I carry pepperspray in my support hand.
I have a ballpoint pen in my shirt pocket.
All except the spray can be lethal weapons.
They fit into an escalation of force plan.
I also carry a cel phone and tactical flashlight.
If you get hassled and cornered by an aggressive panhandler some night,
would you shoot him, spray him, or temporarily flash blind him?
I highly recommend integrated training as offered by
www.insightstraining.com in Western Washington.
And, no, I have no financial interest, merely a satisfied student.
Knives, pens, lights, and phones are also convenient non-defensive tools.
