Explain briefly how it is easier to cut a yam with sharp knife than blunt knife?

A sharp knife has a thinner blade that can easily slice through the tough skin and flesh of a yam with minimal effort. On the other hand, a blunt knife has a thicker blade that requires more force to cut through the yam, making the process more difficult and potentially dangerous. Additionally, a sharp knife provides more control and precision, resulting in cleaner cuts and a more efficient cutting process.

A sharp knife has a thinner, more acute edge than a blunt knife. This means that it exerts more pressure per unit area on the yam, which helps to cut through it more easily. In contrast, a blunt knife has a thicker, more rounded edge, which exerts less pressure per unit area and therefore requires more force to cut through the yam.
