Tools

Tools are a special type of items in Hollow Knight: Silksong giving Hornet both offensive and defensive abilities.

Crests
Crests are required to equip Tools. They present slots for types of Tools, limiting how many can be equipped depending on the type.

List of Tools
Only three categories and six individual tools have revealed so far. The red category groups all presumably limited use consumables. These Tools can be refilled after sitting on a bench and will cost Shell Shards. The effects of the yellow and blue categories are unknown.
