If you haven't heard, the Obama administration has made changes to an old law that banned importation of switchblade knives (the 1985 federal Switchblade Act).
In theory, my old Gerber Magnum Hunter wouldn't be banned by the revised law since it is not imported, but WHAT IS NEXT??!!
Some information is here, Obama administration moves to ban 80% of folding knives.
There is more info at KnifeRights website.
The National Rifle Association is working on this as well. Here is a link to NRA-ILA article
Again, its time to voice your opinion on what you can carry on your person.
