elkins, I would disagree with your view, first here is the law ( less the ballistic knife lanauage to save space):
United States Code
TITLE 15 - COMMERCE AND TRADE
CHAPTER 29 - MANUFACTURE, TRANSPORTATION, OR DISTRIBUTION OF SWITCHBLADE KNIVES
Section 1241. Definitions
As used in this chapter -
(a) The term ''interstate commerce'' means commerce between any
State, Territory, possession of the United States, or the District
of Columbia, and any place outside thereof.
(b) The term ''switchblade knife'' means any knife having a blade
which opens automatically -
(1) by hand pressure applied to a button or other device in the
handle of the knife, or
(2) by operation of inertia, gravity, or both.
Section 1242. Introduction, manufacture for introduction, transportation or distribution in interstate commerce; penalty
Whoever knowingly introduces, or manufactures for introduction,
into interstate commerce, or transports or distributes in
interstate commerce, any switchblade knife, shall be fined not more
than $2,000 or imprisoned not more than five years, or both.
Section 1243. Manufacture, sale, or possession within specific jurisdictions; penalty
Whoever, within any Territory or possession of the United States,
within Indian country (as defined in section 1151 of title 18), or
within the special maritime and territorial jurisdiction of the
United States (as defined in section 7 of title 18), manufactures,
sells, or possesses any switchblade knife, shall be fined not more
than $2,000 or imprisoned not more than five years, or both.
Section 1244. Exceptions
Sections 1242 and 1243 of this title shall not apply to -
(1) any common carrier or contract carrier, with respect to any
switchblade knife shipped, transported, or delivered for shipment
in interstate commerce in the ordinary course of business;
(2) the manufacture, sale, transportation, distribution,
possession, or introduction into interstate commerce, of
switchblade knives pursuant to contract with the Armed Forces;
(3) the Armed Forces or any member or employee thereof acting
in the performance of his duty; or
(4) the possession, and transportation upon his person, of any
switchblade knife with a blade three inches or less in length by
any individual who has only one arm.
The introduction into interstate commerce is of course illegal, but the possession and sale is only limited to certain federal jurisdictions which states are not part of. I understand that you feel you are buying the product which was delivered as the result of a crime, but the only way you could be found guilty of this would be if you consipired to commit the crime of interstate commerce with the seller. Could someone ordering from an out of state dealer be so accused? Maybe. Never seen or heard of it, and I would suggest that in the 20 or so cases this law has been enforced it was only done so after many warnings and the customer base was not effected. In Sal's case there were letters sent to the customers ( I Believe).
