'Bingley's suggestion of the Boker Plus Cop Tool is a good one. I've been using that tool as an GHB/EDC Bag option, for years, in a permitting environment. Problem is, the urban environments where it would be most useful, secure buildings, subways, etc., frown on them. Foolish I agree, especially since it is in no way a weapon-like tool. My substitute is a Pocketwrench. II. A poor substitute I agree. But, in my experience, acceptable almost everywhere.
