Justify : Cutting vegetables with sharp knife is easier than with blunt knife .

Dear Student,
Since area of cross-section of the edge in case of sharp knife is very less compared to that with blunt knife. As such, for a given force, the pressure exerted on the cutting object surface due to a sharp knife is much more as compared a blunt knife. This is the reason why cutting vegetables with sharp knife is easier than with blunt knife. 

Regards
