   What about a combined seatbelt cutter with say a windscreen scraper and or washer jet cleaner.
   Youll need some thin plastic or ply wood
   A paper clip and a blade from a disposable razor
   cut two rectangles of the material identical. place them on top of each other and clamp together
   Mark a point 40mm on one long side and say 15mm on the other
   Draw a line between the two.
   Use a saw and cut from the 40mm side towards the 15mm at an angle until you are half way through then STOP.
   Take the paper clip and straighten one side out so it is like a little needle
   strip the razor blade out of the disposable razor and be careful

   spread epoxy resin on both the inside parts of the two boards.
   you are going to make a sandwich of them
   place the razor blade on the inner edge of the cut you have made the blade edge facing out towards the open end.
   Place the paper clip on the top upper edge with the point sticking out of the board.
   Sandwich both parts together so the cuts align
   leave to harden
   Once hardened sand all edges be careful of the paper clip point
   The lower edge can now be bevelled to form a windscreen scraper.
   and a hole drilled through the top edge to hang the thing up
   you now have a three in one seat belt cutter ice scraper and jet cleaner

   Same as before and its very simple………

   Make an airbag………..and you can use a larger zip-lock bag and inside that bag put three smaller regular bags that contain 1. baking soda, 2. vinegar and 3. baby powder…..use small amounts of all of the above..
