Recently i got a paper cut in my finger while i was writing my assignment.
I asked myself how is this even possible
TAKES THE PAPER
TAKE THE FOLDSCOPE
Though it was cut highly presise by machines in the industry , its not.
I was even able to see the fibers sticking out individually ,it was all shabby and i just looked at my finger how did this even possible.
And the crazy part is the pointy edge….buuut not really.
Its not even really pointy at all.
After some youtube and thinking , understood that this whole sparpness thing is relative to the both materials.
it acts like a saw tooth which is steady enough only at some positions to hold straight and tear the tissues and vesseles.
