survival knife used with a stone. you can carry it anywhere and be prepared for anything!

hey, my name is Nimrod Fieldman , im from the holyland Israel.
this is a project i made for my industrial design school in Jerusalem, we tryed to think of an input that a designer can bring to this exciting field.
i think man always loved to make things, especially knives! and this is kind of a closer between the old caveman and the modern new caveman. the one that know's to print in 3d.
in these files you can manipulate them by scaling so they will fit a stone you have or made. the stones are made by breaking with another one. after you have a good stone you downlod the file and print a handle/ then you put the stone in a pan on the fire untile its hot, cerfully lift it and push it in the right place, after its in the spot you want it, put it under water and it will stay there.
enjoy!
