Re: "My keychain has 2 sizes each ..."
"Out of curiosity, can you still openly carry a Leatherman in UK? Because if that's not "going equipped" I don't know what is"
"Going equipped" isn't quite as cut'n'dried as stated. Circumstances have a lot to do with it. After all, many people carry tools or other items that could be used for nefarious things all the time.
