Relax Woodja, as they said it is bringing them into line and catching up with most other countries. I've been carrying my handy Swiss army knife in my flight bag the last 7 years in NZ through screening (non lockable blade less than 6cm length). There hasn't been a glut of armed and dangerous incidents here threatening the well being of crew or the aircraft since rules were relaxed in 2005/6 ish.
There are far more dangerous things available to pax on board than tiny nail scissors, small knives and golf clubs and there always has been. Aviation security is more about public perception than actual risk mitigation.
After all, when the "rules" came in after 2001 did they also remove/ban aircraft fire extinguishers, wine bottles, drink glasses, duty free, spectacles, heavy metal suitcases, laptops, hot water, rope, belts, teeth, fists, people with martial art training, full beer cans, name badge pins, boots.............think you get the point.
Unfounded hysteria like this does nothing to improve flight safety, streamline air travel or discourage terrorists. I promise to rescind my comments and plead idiocy if there is a flurry of incidents once these relaxed requirements come into effect, but I will be very surprised.
