I understand the fascination with the auto knife and I'm guilty of it. The auto has been romanticized and elevated to a "celebrity" status. I have (1) Buck 110 "switch blade".
After I got my auto knife I soon realized that assited knifes, the ones I longed for since childhood, the ones I saw in the movies, were nothing more than a novelty and after playing with mine I soon had buyers remorse.
Maybe the worse part was my dad telling me they were knifes for dummies and show and not understanding what he meant until after I purchased my own.
Truth be told, I'm embarrassed to admit defying my fathers advice is probably the reason why I spent twice the dollars on what I would have on a 110 that had better steel for a button operated 110.
I also read you can't have a knife collection without a switchblade so that's another train of thought. And I also understand collecting so if Buck makes it and you probably need it. (Withought question you need it).
Where I live it's legal to own a auto knife and posses on ones person in ones home. I can't have it on my person outside of my house and I can't transport it it my vehicle. Overall It pretty useless and the cool factor rapidly diminishes.
