- "A machine part used in ancient machinery. It's incredibly sturdy, and it's not made of any recognizable material. It may come in handy someday."
- — In-game description
Ancient Shafts are materials in The Legend of Zelda: Breath of the Wild. It is a Guardian Part obtained by defeating certain types of Guardians, by searching broken Guardians, or lifting legless Guardians near sources of water using the Cryonis Rune. Link can also purchase them on rainy days from the traveling merchant Teli travels around the Necluda province. Like all Guardian Parts, it is a piece of ancient machinery created by the ancient Sheikah.
Ancient Shafts can be used by Great Fairies to upgrade certain armor. At the Akkala Ancient Tech Lab the Ancient Oven Cherry can use them to forge certain types of Ancient Soldier Gear after Link relights its Furnace during "Robbie's Research". Additionally like Monster Parts, Link can use them to create Elixirs by cooking them with Frogs, Lizards, or Bugs, however this is generally a waste as Ancient Shafts are more useful for crafting Ancient Arrows which can obliterate non-bosses and cause great damage to Guardians. Ancient Shafts drop more rarely than Screws, Gears, and Springs with only Ancient Cores and Giant Ancient Cores dropping even more rarely than Ancient Shafts. As a result Link should avoid wasting them through Cooking and avoid selling them to ensure he always has some on hand to forge Ancient Arrows and other pieces of Ancient Soldier Gear including Ancient Bladesaw, Ancient Short Sword, and Ancient Spear. The Ancient Helm also requires Ancient Shafts though Link only has to forge it once unless the Ancient Helm is sold.

During the Side Quest "Slated for Upgrades", Purah will offer to upgrade Link's Remote Bombs in exchange for three Ancient Shafts. Once Link has provided them, Purah will allow him to use her Guidance Stone to upgrade his Remote Bomb runes to Remote Bomb+ which increases their range, power, and decreases their recharge time allowing them to recharge faster.
