Which knot is typically used to tie together two ropes of unequal size?

The becket bend is commonly used to join two ropes of unequal size effectively. This knot creates a secure connection, allowing for the thicker rope to pass through the thinner one without compromising the integrity of either rope. The way the becket bend is constructed provides a stable and reliable hinge point, making it a preferred choice for situations involving different rope sizes, such as when a smaller line needs to be attached to a larger one.

The bowline is primarily used to create a fixed loop at the end of a rope and is not designed for connecting two different-sized ropes. The sheet bend can also connect ropes but is most effective when both ropes are of similar size; it doesn't perform as well when the size difference is significant. The double fisherman's knot, while robust for joining two ropes, works best for ropes of similar diameter and is often used in climbing or fishing contexts, making it less suitable for joining ropes of unequal size.
