I took the "hiding in plain sight" approach. I attached a removable split rinf to my small leather Palm portfolio's zipper pull. To this I attach a Leatherman Juice, Fox whistle, Photon II and a CPR mask. Occaisionally, folks would as me about it and I would explain why I was carrying them. After 9/11 this explanation met with interest instead of objections. I also have money, phone card, quarters, razor knife and a cheat sheet in the business card pocket on the inside.
