What's kinds of tools did the Sioux made and use?

The Sioux used almost every part of the buffalo for many things (tools).
The bones were used for toys, tools, painting sticks, and an awl (a special kind of needle).
The muscles were used for thread and bows.
The horns were used for spoons and cups.
The stomach was used for a pot for cooking and carrying food and water.
The tongue was used for special religious celebrations.
The dried buffalo droppings were used for fuel for camp fires.
The hair was used for ropes, fancy belts, and decorations.
The ribs were used for sleds.
The hide was used to make rawhide (for drums, rattles, and bags to hold dried meat and clothing, glue, and splints) and to make soft cloth (for bags, moccasins, clothing, pipe holders, and tipis).
