According to my read, it's INTENT. If you are a dirtbag, it's illegal. if you are an upstanding citizen, it's okay. Call it a HUNTING knife and you were using it for chores in the yard, you'll be okay. NO double edges.
If in doubt, contact the local state's atty or a criminal defense atty, but the above is from a very good source and Levine has a lot riding on his rep.
HOWEVER, as The Last Confederate states above, city ord will supercede state law often. Oak Park, Evanston, Chicago, bastions of all that would benefit the scourges of our society, seem to think you have no need for anything more than a dull spoon and a pair of running shoes. Beware the idiocy of the Cook County mindset. In DuPage, just don't do anything stupid with it.
