Pepper spray is not just for girls. Its an important component of a "use of force" continuum. Proper use of pepper spray does require some training just like any other tool. Keep in mind the legality of using it. Also keep in mind if you spray your self accidentally ,you could be incapacitated. Also, (from personal expirience), sometimes it works great, and sometimes not at all.

I carry key defender too.. nice peice of gear IMHO.
I will use anything to my advantage . sticks, stones, bottles, nails, teeth, knives, guns , and yes girly pepper spray. DEAL WITH IT
