BTW F3G not "stamping my foot" just stating the blindingly bloody obvious.....it's illegal to take a knife on board a flight in the UK!! Clearly there are people here who can't?won't grasp that.
Very dramatic...but wrong.
I don't think either F3G or Paxboy suggested they illegally took knives onto aircraft or supported anyone doing so..that is a very serious accusation to make. Paxboy said he puts his through the x-ray machine, which is standard security. One therefore presumes that his blade, whether on a knife or otherwise, meets the requirements and is less than 6cm which is perfectly legal.
Realising this could be a contentious point, I have added the relevant passage from the government website..my highlight.:
