Just so we are talking about the same thing, here is the statute, U.S. Code, Title 15, Chapter 29, manufacture, transportation or distribution of switchblade knives as I copied it off a site called Findlaw some timeback. Maybe it's been revised or amended. But I don't see anything in this version that limits it to federal property.
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.
***********************************************
and:
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.
**************************************exceptions: 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.
********************************************************
As I said, the law is whatever a court says it is. If you want to take a chance that some cop snags your blade and a judge will agree with your interpretation, why, my goodness, that's the American way.
