How to Tie the Thief Knot
The Thief Knot is not really what I would call a practical knot, the problem with the thief knot is that it can easily fall apart if pulled from any direction. It was as I understand it a form of sack knot, but rather than just keeping a sack closed, it would indicate if a sack had been tampered with! Below you will see what ABoK has to say about the Thief Knot.
Ashley’s Book of Knots on the Thief Knot
ABoK 1207 “The Thief or Bag Knot is also called Bread Bag Knot. It appears very like the Reef Knot, but there is one real and scarcely evident difference. It does not consist of two Half Knots. There is a legend that sailors tie clothes bags, and bread bags with this knot and that thieves always retie them with Reef Knots and so are inevitably detected. It is a pleasing story that should encourage honesty.

I personally like the thief knot because of the story about being able to see if a bag has been tampered with or not. I like to show this knot to people and demonstrate just how easily it falls apart.
