The sickle is one of the basic tools used in Harvest Moon.
The basic sickle cuts a 1x1 square of grass. It is one of the starting tools, and takes two energy points to use each time it is used.
The upgraded sickle is called the Super Sickle. It cannot be obtained at the beginning of the game, but will become available later. It can either be purchased or gifted to the player by the Harvest Gnomes. This upgraded sickle can cut a 3x3 square of grass, and uses three energy points.
The sickle is used to clear weeds, and cut grass which produces fodder for livestock.
