I will say one thing Tourist. I find it amusing you lampoon the carrying of a small implement like the Hideaway while simultaneously lampooning the mall ninjas of the world who carry 40 pounds of dangerous metal about.
If I were truly, truly, over paranoid, over dedicated to my personal protection, I would carry a Bagwell Hell's Belle. Lynn Thompson would be there to teach me how to conceal it.
But, as you suggest, I am not a Jedi. I instead carry a much smaller knife made for the worst situation I can fathom that doesn't require me to change my life style or wardrobe and costs maybe 1/20th as much.
I appreciate Striders, Busses, and Mercworx offerings for what they are, but I've no plans to ever buy one. That's money better spent on a new Calculus reference text.
