The whole problem here is one of illogical reaction to a perceived threat. The government is not trying to protect passengers and the general public with these confiscation policies, but merely applying clumsy public relations tactics in an attempt to make us feel safer.
The fact is, the main threat the government is concerned with is another hijacking and use of a jetliner as a weapon. However, if an assailant can't gain access to the cockpit to threaten the pilots, there is virtually no chance of a repeat of 9/11. The only reason the use of boxcutters was successful on 9/11, was because the control of the plane was taken away from the pilots. A clear "no open door" policy when it comes to the cockpit, combined with reinforcement of the door physically, should prevent the recurrence of these types of hijacks.
The confiscation of small tools, nailclippers, etc. does nothing to address the real next threat, small explosives. It should also be recognized from the recent attacks in Spain, that the desire of Al-Qaeda is for mass effect, not just killing large numbers of victims. The use of jetliners as weapons has had its impact. It is far more likely that the next large attacks will be against so-called 'soft' targets. Buses, railways, county fairs, business conventions are all more likely targets than airlines, and are vulnerable regardless of the safety of our passenger air system.
BTW, just ask any prison warden, guard, or inmate whether it is possible to craft a useful weapon from plastics or other materials which could evade detection by screening systems.
Go ahead, ask 'em. /ubbthreads/images/graemlins/thinking.gif
Back on topic...I kinda wish someone made a multitool without a knife blade at all. They always seem thin and fragile..I would prefer another tool in place of the knifeblade (like a 1/4" socket stud), and would just carry a quality folder for my blade needs.
