My reasoning might seem odd to some people, but I carry two, and here's why: my BM707 IWB for taking care of absolutely everything, and the diminutive AG Russell Ultimate Pen Knife hidden in an equally diminutive pocket that nobody would ever think to look, just in case someone drugs me, (or shoots me in the chest with rock salt) and then takes away my 707, ties me up, and buries me alive, like in Kill Bill 2. No, I'm not joking. While watching this scene in Kill Bill 2, I think to myself, "Gee, I bet she's glad that she has that little blade, and ever since I have carried a hidden blade stashed away just in case this kind of situation, (or something else equally crazy) occurs. I guess you can say I enjoy being prepared.
