Sir:
Hand tools are nearly useless if not properly maintained. This concept seems under emphasized in preparedness literature.
One should have a stash of assorted files and sharpening stones, as they can be broken or worn out.
Items like hacksaw blades that are nearly impossible to make at home should be acquired in quantity. People should also buy a quantity of tool steel and drill rod suitable for fashioning cutting tools.
Thanks for your advice on your blog site and for your novel “Patriots” . Regards, – Jim J.
