every state has its own laws on carrying auto knives.
for cops it would depend on the dept, but some cops do have them. and most cops have some sort of 1 handed tactical folder.
what are the high dollar tactical models? benchmade ?
i would say mostly knife nuts are going to buy high dollar knives, of any type. but those that carry them are prolly few, mostly because of state laws.
in kali autos are illegal to carry(felony), but i know one woman who has one for self defense purposes (dont know if she actually carrys or not). a concealed handgun is less of a problem(misdeamenor) but still illegal.
with all the 1 handed openers now, why bother spending the extra money on an auto, or have to deal with state laws and cops if they find one on you.
autos are fun and sexier than your average knife, but a 1 handed tact knife will open just as fast if not faster (depending on the user), even if its slower, does a few milliseconds mean much ?
