Whetstone

Whetstones are an item that can be obtained through searching gravel. As with most crafting utensils, they can be used multiple times with durability being used with each craft. Different crafting recipes use up different amounts of durability.

Trivia

 * In the item's description, "porous" is misspelled as "pourous".
 * There is a glitch with the Whetstone. Picking the item up in your inventory and swapping it with another Whetstone will cause the durability to match the one you were originally holding. This can be used to get infinite durability.
