What differentiates a Granny Knot from a Thief Knot?

The correct answer emphasizes the structural differences between a Granny Knot and a Thief Knot. A Granny Knot, while it may appear similar to a square knot, is improperly tied. It results from tying two overhand knots in the same direction, which can lead to misalignment and a lack of stability when under tension. In contrast, a Thief Knot, which is recognized for its characteristic of being misaligned, is also typically tied incorrectly and is known for its tendency to slip or come undone easily.

Thus, the statement regarding the Granny Knot targeting its incorrect structure as a square knot and the identification of the Thief Knot as misaligned accurately reflects their characteristics and the reasons why they differ from each other. The emphasis on their knotting techniques helps highlight why a Granny Knot is not secure and why the Thief Knot's misalignment compromises its integrity as well.
