Yes, blade locks are going to be required. Plus, you will have to submit to a background check before you are allowed to buy one. Plus, there is a 10 day waiting/cool-down period. Also, you will not be allowed to buy more than one box cutter every 30 days.
Also, high-capacity blades are illegal, and blades shorter than 18 inches will require a special tax.
Not to mention, you are not allowed to carry a boxcutter concealed, and not in a school, church, bar, restaurant, court building, or any other place where it is restricted by law.
