I found this belt interesting... http://radenpayas.com/2009/02/09/my-stupidity-almost-put-me-into-jeopardy/
I find it disturbing (and kinda pathetic) that people carry weapons hidden in their belts. It's not even a nice looking belt.
It's actually depends on the place where you are living... If you are living in place with a lot of snatchers and robbers I think protecting yourself is not bad...
Only problem is that he'll have to unbuckle the belt first, if someone jumps out on him, he'll not have enough time, space, cool-headedness to react. So it's pointless really.
So you're confronted by a "snatcher" and you start taking off your belt? Yeah right... that's going to end real well....
