Knot Thimblejack's Cache is a container that is left behind by Knot Thimblejack in Dire Maul. Knot is held captive by the Gordok Ogres and when you free him, he leaves behind his cache. In order to free Knot, you need to get the [Gordok Shackle Key] which drops off the ogres. Once you have the key, you talk to Knot which starts the quest Free Knot!. After he is free, he will leave. If you are planning on doing the Gordok Ogre Suit quest, make sure you complete it first before freeing Knot.
