I am not sure when Sal said there were a fad, but please remember he paid a $400,000.00 fine and loss of merchandise for using the USPS to mail butterfly knives accross state lines after US Customs started an action against his company for importing parts to assemble them in the US. I am sure he was not happy about that and most likely would not want to test the AO waters in the legal area. I don't know why he was singled out by US Customs when China ships all knids of switchblades and butterfly knives illegally into the US fully assembled. I would have to guess this lead to the "fad" comment. I strongly believe tha AO system will be around for awhile as it has a great fun factor, and Kershaw has a quality product. Many states ( NY for one) feel they have already dealt with the legal question on these knives, since you can still flick them open, and therefore in the state of NY they are Gravity knives reguardless of the AO feature....
