A line knot tying apparatus and method of use is disclosed that assists in joining first and second line free end portions. The knot tying apparatus includes a housing with an aperture therethrough that is slidably engaged to an extension element wherein an element biases the extension to a closed state that can be manually pushed into an open state. Also a helical coil with continuously increasing pitch line distance is attached to the housing. Operationally the first and second line free end portions each have a manual removable slidable engagement to the helical coil with opposing free ends that are wound in a plurality of loops about the opposing line then being secured by the extension element in the closed state. Then manually pulling the non free end line portions apart from one another to form the knot, further releasing the opposing line free ends from the extension element.
