A massive cleaver is more effective for chopping vegetables than an equally sharp knife because of which of newton's laws?

Newton's 1st Law

Explanation:

A knife is surely sharp but the cleaver requires less force as compared to the knife because of it's advanced design strategy. A knife can only chop one at a time but a cleaver is of more mass that means less force on a unit area is required to chop down the vegetables. If a arrangement of knives is so that they can perform simultaneously than they will require less time to get the jo done.
