With all the talk about tactical pens and kubatons, keychain flails, quasi-legal knucks, and blinding lights, etc.. I'm wondering if anybody has actually used those in a confrontation. And if so, what happened and how did it turn out? I'll go first: My one experience was on the receiving end of a fist load (i.e. roll of quarters). It was effective, and very unpleasant, to say the least.
