Apr 1 at 0:30 comment added Jim Clay @AlexP Thorns are a good idea. Thanks for that. Regarding rocks being sharp- often not as much as you think. It's often surprisingly hard to cut through stuff. I once watched a man try to put a cow out of its misery after it was hit by a train. He tried to cut its throat with a knife, and no matter how hard he leaned in, could not get the knife to puncture the skin. Granted we are not cows, but you get the point.
Apr 1 at 0:30 comment added Jim Clay Sorry for any vagueness. I want to find a way to extract non-trivial amounts of blood (think a pint or more) without killing the person, and having no technology.
Mar 31 at 21:17 comment added AlexP In fairy tales, the canonical no-metal no-stone method of having the fair princess shed a little blood is to prick her delicate rosy finger on a rose prickle... And anyway, if rocks are available, I just don't see the problem -- broken rocks have sharp edges, don't they?
Mar 31 at 20:39 comment added Fallenspacerock @Jim Clay you should maybe clarify what you want as it's kind of hard to figure out what you are asking.
