Be careful with this item...
They have been banned... They are illegal to buy... sell ... and ESPECIALLY possession of it anywhere...
and some states have strict laws on selling and purchasing these...
Shipping it to the wrong person in the wrong state ...over state lines can also make this a fed matter...
Selling or possessing this can lead to problems...
"In the USA, switchblades remain illegal to import from abroad or to purchase through interstate commerce since 1958 under the Switchblade Knife Act (15 U.S.C. §§1241-1245). However, a 2009 amendment (Amendment 1447) to 15 U.S.C. §1244 provides that the Act shall not apply to spring-assist or assisted-opening knives (i.e. knives with closure-biased springs that require physical force applied to the blade to assist in opening the knife ".
JFYI.
Years ago I bought one at a yard sale and found all this out after from a LEO ...
I snapped it in two parts and threw it in the trash.
IF you have this ON YOU... you are gonna get arrested... period.
