The Metal Sickle in ARK: Survival Evolvedharvestsresources from some of the renewable resources at a higher efficiency and yield than by hand. Made out of sturdy wood and metal, it is cheap yet reasonably effective. However, it is not commonly used, as a wandering tamed Gigantopithecus can be used to autonomously gather fiber, and other tames can manually harvest at greater efficiency than the sickle.
Items which use stats, namely Melee Damage, Durability, Armor, Hypothermic Insulation and Hyperthermic Insulation, have Item Quality, with higher quality items having better overall stats (though lower quality items may be randomly superior in an individual stat). Items with improved quality can be obtained from beacons, loot crates, and other forms of loot drops (such as from killing predators), while blueprints of higher quality items are obtainable only from beacons and loot crates. Items with higher quality can cost substantially more than primitive versions.
