I carry my knife everywhere in deep pocket but it's not illegal in California. If it were illegal to carry any kind of knife I would probably hold carrying to work hours because the chance of being questioned is low in that situation. But I would never take it out to the bars or out at night when everyone is suspect. Not sure how hard core the police are in Sweden but out here they take it pretty seriously. I did get busted when I was in college because my roommate was smoking pot in our Dorm and set off the fire alarm. I was 19 and the cop came in my room and found a balisong and half a bottle of Jack. He confiscated my knife but didn't bust me for it because I told him I just bought it online cause I thought it looked cool. He was like "That's a butterfly knife man! You can't have that!!!". Guess I got lucky on that one.
