A lasso knot, also known as a honda knot, is a round-shaped knot tied at the end of a rope to form a lasso for roping calves. The knot is formed by tying an overhand knot in the end of the rope, and then a second overhand knot through which the smaller knot is passed to create a circle.
Lassos are used to capture cattle on ranches and for show events in rodeos. Lassos are best formed from stiff rope. The end of the rope passes through the circular honda knot to form a lariat or noose. The rope slides freely through the circle formed by the honda knot because of its stiffness, and the stiffness also makes it easy for the cowboy to keep the noose a particular size or to loosen it if necessary.
The cowboy makes the loop at the end of the rope the proper size, throws the loop over the calf's head and pulls it tight. The rope slides freely through the lasso knot to hold the calf firm. The other end of the rope is always secured to the saddle horn to put the tension of the capture on the horse and not the cowboy. The lasso knot is also sometimes called a bowstring knot because the circular knot works well for attaching a bowstring to a bow.
