Barack Obama was recently on a visit to Denmark in order to find inspiration for further "adjustments" of current US knifelaws.
He was so inspired that he will put the following into motion:

Banning knives over 4"
Banning pointy knives
Banning one-hand opening knives
Banning folders that lock
Knives are only to be carried in woodland areas

Man I feel for you! It is even stricter than here in DK.

As from April 1st the new laws will be in effect.
