Second, the Feds do not have the power to ban a product - they can only limit the interstate sale of that product using the commerce clause.

A ban by any other name.....
By using the incredibly hyper-extended commerce clause, the federal government has gotten into areas completely out of their jurisdiction; including this one. As Ron commented earlier, the fact of knife regulations being entertained by the federal government is ludicrous. In actuality, the issue is and should be an import issue only. The remainder should fall into states rights as per the constitution:
Article one, section 8:
To regulate commerce with foreign nations, and among the several states, and with the Indian tribes [emphasis added]
And, of course, the 10th Amendment:
The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.
And there lies the rub...it's NOT the federal governments business to establish ANY state policy!
