There’s a bit of a tendency to focus on firearms here in the prepping and survival community. That makes sense, when you think of it from the viewpoint of self-defense
Many of the components presented here in Part 3 came out of my personal Pocket Survival Kit and require proficiency in their use to be even minimally effective.
I always carry a knife for self-defense as it helps that knife laws are less restrictive than those for concealed carry and you won’t get in too much trouble.
