Abstract
Abstract The device facilitates tying a variety of knots similar to the commonly termed nail or tube knot. It is flat and generally rectangular with a hole at one end and a fork at the other. The fork is two-tined, narrower than the remainder of the device and centered widthwise on it. The profile change from full width to fork width forms angled shoulders at the base of the tines. The depth of the slot between the tines is greater than the distance from the tips of the tines to the junctures of the shoulders and the tines by an amount at least equal to the width of the slot between the tines. There is a second slot called the side slot, normal to one of the long edges of the device, with a depth in the range of 1/4 to 1/2 the width of the device, 1/3 being preferred. In a preferred embodiment the device is 3/8 of an inch wide, 0.060 of an inch thick and 2 inches long with the fork occupying 1/4 of the length.
