I reckon your probably nearly there matey, have you got a cork screw on your penknife?( I know you can push them in or shoe them out but it's nice to do it normal once in a while) I would really consider putting a reasonable amount of paper money in a little ziploc, takes up no room and is always welcome when you spot a nice bap but have left your wallet in the car, maybe a small turn of cotton threaded on a needle wrapped in a little scrap of leather, for the odd fix here and there, i tend to have these bits on me when ever out, I don't have a survival kit to carry about but just things to do odd jobs with or even just to play with when sat under a tree if out in the rain.
