Location
Crafted items, harvested items, building materials. Do not use on Tool or Weapon pages.

Use
Defines the required tech level needed to craft an object, harvest an item, or obtain a building material. Early in the technology progression, this property isn't required: an object is crafted without tools, or an item can be harvested with bare hands. Later, this value will depend on the tech level of the tool or knowledge needed to craft/obtain the item.

If nothing special is needed, you can leave this property out, or set it to Scavenging.
