EDC back pack

Hi, i'm working on my edc and thought about having a pouch for my back pack, i't would function like a go bag but in a much more smaller version and in a small baf in my back pack, what stuff wold I have in it? Due to laws in my country I'm not allowed to carry a gun or pepper spray but nifes are allowed so I'm thinking of havin one of them in there, need ideas, thanks
