I am not at all sure that you can bring a plastic or lexan knife through security. ( by rule I mean not practicality )

From http://www.faa.gov/apa/tipbroch.htm :
When you are preparing for your trip, remember to pack smart — pack safe. You cannot bring the
items listed below on your person or in carry-on luggage.

Knives of any length, composition, or description.

It's the first thing on the list folks...
