Which knot is the square knot variation used for joining two lines of different sizes?

• A. Bowline
• B. Square knot
• C. Sheet bend
• D. Clove hitch

Answer: (C)

When you need to join two lines that aren’t the same diameter, you want a knot that distributes the load and grips the differing sizes without slipping. The sheet bend does exactly that: you form a bight in the larger line, pass the end of the smaller line underneath that bight and around the outside, then tuck it back under itself. That setup locks the two ropes together despite their size difference and under load. Using a square knot for unequal sizes isn’t reliable, as it can slip or capsize when the diameters differ. Other knots like the bowline or clove hitch serve different purposes (loops or attaching to a post), so they aren’t suitable for joining two lines end-to-end. For extra security with slick lines or very different sizes, a double sheet bend adds an additional turn.
