Disclaimer- I don't live in Illinois, never have, I am not a lawyer, I do not claim to be an expert on, nor do I claim to be particularly knowledgeable about Illinois knife laws.
But just for the sake of discussion, and because I'm bored, I did some quick research-
Here is a link to Illinois knife laws on the official Illinois government website-(paragraph 2 relates to "daggers")(Disclaimer- I do not know if any changes have been made to this statute since it became effective in 2017)-
https://ilga.gov/legislation/publicacts/fulltext.asp?Name=100-0082
And here is a link to a synopsis of Illinois knife law from the American Knife and Tool Institute (Disclaimer- I do not vouch for the accuracy of any information on this site)-

Two things that stand out to me-
1. I can't find any legal definition in Illinois law for "dagger". That doesn't mean that one doesn't exist, but I sure looked, and I couldn't find one.
2. I looks like it is legal to carry a "dagger" as long as you do NOT do so "with intent to use the same unlawfully against another".
My layman's interpretation is that it's legal in Illinois to carry a "dagger" as long as you don't have the intent to use it UNLAWFULLY against other people.
But hey, I certainly wouldn't expect anyone to make legal judgements based on my interpretations
.
My advice, when in doubt, find and consult a local attorney who is very knowledgeable on the subject of local weapons laws. As one who carries a knife, it never hurts to know a good criminal defense attorney should a misunderstanding arise.
