"A farming tool used to collect hay efficiently. It's light enough to be used by anyone. The four prongs are very sharp."
The Farmer's Pitchfork is a two-handed spear found in Breath of the Wild. It has a base power of 7, and is typically found in urbanized areas, such as within Hateno Village, but it can also be seen in the possession of Red Bokoblins on occasion. It does a surprising amount of damage considering it isn't designed for combat, so it can be useful if the player has a deficiency of traditional weapons.
Early on his quest, Link can find a Farmer's Pitchfork just outside of the Woodcutter's House on the Great Plateau. Given it's relative power, it is a fine weapon to have during the first part of Link's journey.
The Farmer's Pitchfork is a weaker weapons than that of the Farming Hoe, but it does have superior durability. It also attacks at a faster rate and has a longer reach than the Farming Hoe.
