These are not "top of the line" CRKT knives. They lack the serviceability and features of more expensive CRKT knives. No Outburst (assisted opening), no LAWKS (double locking feature when open along with the frame lock), none of the famous designers. I would much rather have the deal that was offered a while back for their Triumph models for $45.00, I got two and still love them. That said in the realm of 8 buck knives (plus shipping) you are not likely to find anything as nice much less worthwhile at all. If it fits your needs go for it.
However you may want to check Amazons sales going on with knives right now. They recently had a sale where many brands like Kershaw and CRKT were $10 off purchases of $50 or more. Many of those same knives have dropped in price since that sale is now over, many under $20 that are pretty nice and if purchased over $25 qualify for free "super saver" shipping. Might get a better knife or two for not too much more when all is said and done. Worth a look at least. This is what I would do and have several nice knives including CRKT's. I just picked up a My Tighe to add to the collection, much more expensive than these but I would rather spend the money for a better knife. And if I were going budget shopping I would go for one of those sub $20 Kershaws.
And yes State laws vary and do not always make sense. The blade length of folding knives has to fall within certain lengths, usually not too long but sometimes not too short.
So then Swiss Army knives would fall under that category and really would you rather get poked by a 2 inch folder or a 3 1/2 inch folder? On the other hand for example in my State there is not the same limits on length of fixed blades, it is legal to carry a sword but not a folder over 4 inches. The outburst or other "assisted open" names for manufacturers knives act very much like switchblades but are legal in most areas as they do not open by the push of a button but rather by beginning to open them with a thumb stud or flipper where a torsion bar or spring takes over, a nice loophole I think. But while cool and useful the old saying "never bring a knife to a gunfight" should be observed!
