Answer 2

Answer:

blunt knife hv rough edges

Explanation:

sharp knife cuts objects better because of its very thin edge, a large pressure can be created on the object when the force falls over a sharp small area of our hand. And this large pressure results in the cutting of the object easily. A blunt knife does not cut the object easily because it has a thicker edge.
