Abstract
A line tying device especially useful for tying a fish line to a fish hook or to another fish line. The line is helically wound a number of times around a mandrel body; the free end of the line is then passed through a groove in the mandrel body into the space circumscribed by the helical windings. A depression in the tip end area of the mandrel body keeps the helical winding in place; after the windings have been formed a pulling force may be exerted on the free end of the line to draw the wound area (knot) off of the mandrel body.
