A twist knot, also known as a twisted knot, is a type of knot characterized by the intertwining of two or more strands. This type of knot can be used in various applications, including climbing, boating, crafting, and more. The twisting action creates friction, which helps secure the knot. Twist knots can vary in complexity and construction, with some being relatively simple and others more intricate.
