Sickles are used to harvest Grass, Wheat and Industrial Hemp. Jade will give the player their first sickle. She will also trade the player for a shears until the Blacksmith is built, at which time the player can buy a new sickle if they lose theirs. Be careful with the upgraded sickle, as it is easy to break more than one intends to. Also, Grass and Industrial Hemp can be harvested from the top block, which will allow the crop to regrow without replanting it.
