Illinois knife laws?

[lawrra]

I will be heading to my college roommate's wedding, unfortunately located in Illinois, this Saturday and was wondering if there is a blade length restriction for Illinois. I would like to take my Spyderco, but it may be a little large. I will have my carry gun, unloaded and locked in the trunk to be compliant with the Repub...state laws. I like to be able to defend myself in the event of an unfortunate situation. Experiences and cited laws/statutes are appreciated.
