Knives are arms protected by the second amendment. They have been arms used by every military since the beginning of time.
I love the effort, but some Hughes type will slip in the poison pill just like they did to the FOPA. In the FOPA, it was the absolute ban on manufacturing machine guns for 'civilian' ownership after May, 1986. So, what will it be for the KOPA? A ban on the manufacture of folding one-hand opening knives?
These things are just an opportunity for the FedGov to do what it does best: TYRANNY.
