sharply edged instruments cover less area and therefore exert high pressure on trees and they get cut easily

In science, the terms go like this.
Pressure is equal to force divided by area Based on this formula, it can be said that when high pressure is exerted in small areas, then the force is required.
Hence the knives, blades, and other things are made with a sharp edge.
