String Figure: Jackhammer

Posted in string figures by pgadey on 2020/10/25

This figure was invented by Joseph D’Antoni of Queens, New York.
These instructions were adapted from String Figure Magazine Vol.6(4) Dec 2001 p. 15-17.

  1. Form Opening A
  2. Release the little loops.
  3. Rotate the thumb loop away from you, and place it on to the little finger.
  4. The right thumb enters the index loop from the proximal side and gets the radial little finger string and returns.
  5. Release the right little finger loop.
  6. The left index loop is transferred to the left thumb.
  7. The left little finger loop is transferred to the left index.
  8. The index loops are rotated towards you on to the thumbs.
  9. All the fingers enter both thumb loops from the distal side.
  10. Flex the strings back and forth to animate the Jackhammer
