AtlanticFlyer. I fear your efforts have been in vain. You could have happily walked through security in LHR with your Mach3, and not an eyebrow raised. There is not much you can do with a mach3 razor, apart from shave yourself. On the otherhand there is no way on earth that you could have purchased nail clippers airside. I think you will find the rules internally consistant, in that respect at least.

THESE are razor blades!
