A tool to assist with hand-tying of knots in balloons, cords, and the like. The tool has a head consisting of a hollow tube with an opening running the length of the tube. The tube is typically tapered with a flange toward the larger end, and the opening is incorporated at an angle nonparallel to the center line of the tube, forming a notch feature that passively retains material on the head until removed by the user. The head is connected to a handle with two or more functionally independent finger loops. The tool may be retained on the hand without unduly impeding dexterity and provides for greater control of the tool when in use.
