Which knot is most appropriate for joining two rope ends of different diameters securely?

• A. Sheet Bend (Double Sheet Bend for larger diameter differences)
• B. Bowline
• C. Square Knot
• D. Overhand Knot

Answer: (A)

When you need to join two rope ends that differ in diameter, you want a knot that grips both cords and resists slipping under load. The sheet bend is built for this exact job: the thinner rope passes through a loop in the thicker rope, then around the outside and back under itself, creating a secure bite that distributes the load between the two ropes. If the diameter difference is large, using a double sheet bend adds an extra turn around the thicker rope, increasing friction and reducing the chance of the knot untying or slipping. A bowline creates a fixed loop and isn’t meant for joining two ends. A square knot works best with ropes of similar diameters and can slip or capsize when the sizes differ or under heavy load. An overhand knot is a simple stopper and isn’t a reliable way to join two rope ends together. So, for securely joining two ends of different diameters, the sheet bend—and the double sheet bend for significant diameter differences—is the best choice.
