Red whats the thing to the right of your multi tool?My advice? Chuck the tin in the bin and get hold of a belt pouch (possibles pouch). Put in that the stuff that's useful and handy to have on your travels and use it - regularly. Replace the things that don't work, aren't necessary or break. Upgrade when you need a better item.
Mine contains all sorts of gubbins. Plasters for when I get a blister or a cut, some headache tablets, a small torch, a ball of string, a lighter.....you get the idea. No need to duplicate stuff that you carry on your pockets.
Let me show you some of mine - this is my "woods" pouch. The black thing is a small monocular for watching game etc.
This is my every day pouch that lives in my jacket pocket

You get the idea...use the stuff it contains so that you know that, if you need it, you know how to work it and that it won't fall apart on you!
