Question

4. Why does a sharp pencil hurt more?​

Answer 1

Answer:

Notice that the sharp knife has a very small area of contact with the surface, while the dull knife has a much larger area of contact. If both knives are pushed down with the same force, the sharp knife will exert a much greater pressure on the surface than the dull knife - and pressure cuts.
