What's in your bag? / Everyday carry (EDC)

In my previous life where I'd work as an electrician, I'd always have a Swiss army knife with me - handy for preparing meals. That was its only use. As I don't do that job any more and don't hang around on building sites too, I've got no need and lost it too. :(
But I'm still surprised how many would carry a knife with them.

Apart from that; as I hate it to carry things in a pocket, I have various shoulder bags with the following items, that vary according to what I need for the day;

• keys - the only item that is automatically checked before door is shut.
  
• wallet
  
• phone, which I always forget
  
• pencil case
  
• notebook (an actual note book)
  
• map, usually basic and compact - I don't believe in fancy digital maps
  
• depending on bike I'm going to use, there might be tools thrown in
  
• water bottle, always!
  
• on a lazy day where I take the train instead, a book or at least something to read..
  
• smoke stuff
  
• litter, because my bag always gets messy and is seldom emptied properly
  
• maybe clothes - I always have a picture about the weather for the next 24 hours in my head
