The knot tyer in accordance with the present invention includes, a hollow, elongated body member with a coil expansion spring mounted tubular piston therein and a release thereon. The hollow, elongated body member has a tubular piston slidably mounted and constrained within a cylindrical, hollow bore therethrough. The tubular piston has a first shoulder, a second shoulder, and a groove extending around the diameter of the tubular piston. The cylindrical, hollow bore in the rear end of the hollow, elongated body member accommodates in free longitudinally sliding manner a first shoulder on the tubular piston as well as a coil expansion spring encircling the tubular piston. The cylindrical, hollow bore in the front end of the hollow, elongated body member accommodates in free longitudinally sliding manner a second shoulder and a groove on the tubular piston. The release is pivotally attached to the hollow, elongated body member by a pin, which pin allows the release to pivot on the external longitudinal axis of the hollow, elongated body member. The tubular piston has a grooved front end. The front end of the tubular piston is grooved so as to be open and hollow internally.
