The "dalgıç düğümü," or "diver's knot," is a type of knot commonly used in various water-related activities, such as scuba diving and fishing. It is designed to securely fasten lines or ropes, ensuring that they do not come undone under tension. This knot is particularly useful for attaching gear or securing items in wet environments. To tie a dalgıç düğümü, one typically creates a loop and wraps the working end around the standing part several times before passing it through the loop. This method provides a strong hold, making it a reliable choice for maritime applications and outdoor adventures.
