THAT is a story i would be very curious to hear… but if you look at the whole stuff that is build in some huts or caves in the middle east, lets just say i wouldn’t rule it out.

You can build a weapon with common tools you find in any metal workshop.

Story time:

Right after the war my grandfather - a locksmith by profession - build a cap and ball revolver in his workshop just with the tools he had and scrap metal.
