Thanks for the feedback.

>>Working as a cop, it became de riguer to notice who had a knife clipped to their person<<

Was that information useful?

>>It also became quite obvious that the bad guys were paying attention to who had knives clipped where.<<

Not sure I see "bad guys" knowing that I'm armed as a big negative- it would seem worse for them to think me unarmed. There's some downside to their knowing where it is, I suppose, but then that would apply to the sidearm of a uniformed policeman as well, wouldn't it?
