My family are planning on going to Italy and the Vatican City is one of our stops. Is their a Swiss Guard pocket knife I can buy. That swings back in the handle not like a knife.

I am an 18 year old female and often have to take the bus or train home late after work. I carry a small can of pepper spray and a miniature Swiss Army knife in my purse or pocket for easy access (or use the hand strap on the pepper spray to keep it in sight), as I have been harassed several times late at night. So far I have never had to use either, but a friend of mine told me recently that carrying this little knife in my purse is illegal in the state of Oregon. I’ve done some research and all I have found is that I cannot conceal a knife that swings into position by force of a spring or by centrifugal force, but does this include my little Swiss Army knife? There is no spring, and I don’t know and don’t think that it counts as centrifugal force if I have to use the little notch to pull the blade into place.
Any information on the subject would be appreciated. If I have to leave the knife at home I will try and find something else more appropriate or just stick with the spray.
